In this session, we have Prof. Dr. Schulze as a guest to detail the biology and neurobiology of learning and memory.
Abtract: Brains process information from sensory organs to create an internal representation of the world. To do so, information not only has to be stored, but evaluated and selected based on previous experience. This process enables organisms to control their behavior and thereby interact with the world around them. In the talk, I will describe how biological brains fulfill this complex task. I will describe how information is stored in biological neuronal networks, and how these memory functions are influenced by experience and emotions. The differences in information processing and storage between biological and computer systems will be described, and possible implications for artificial neuronal networks will be discussed.
Short Bio: Holger Schulze studied biology at the Technical University of Darmstadt, where he graduated and did his PhD on sound processing in the auditory cortex of Mongolian gerbils. In 1996 moved to the Leibniz Institute for Neurobiology in Magdeburg, where he started his own group and worked on mechanisms of learning and memory in the auditory system. In 2003 he finished his habilitation in physiology at the Medical School of the Otto-von-Guericke University in Magdeburg. In 2007 he followed a call to Erlangen, where he is an associate professor for experimental otolaryngology. His main research topics now are the neurophysiological mechanisms of hearing, tinnitus, and sleep.

In this session, we have Prof. Dr. Schuller as a guest to detail the concept of Ambient Health Intelligence.
Abstract: The vision of accompanying Artificial Intelligence providing in situ health diagnosis wherever we are has long since been depicted on the big screen. More recently, however, former science fiction is steadily leaving the fiction grounds as more and more wearables feature more and more sensors with increasing features of intelligence. Already today’s smart watches and trackers monitor our heart rate, blood oxygen level, and recently also started to “listen in” equipped with microphones. But the promise held by such mobile health does not stop at recognising heart attacks, and with the IoT, sensing can embed surrounding sensors’ information leading into the era of Ambient Health Intelligence. This talk highlights the implication on the AI side facing challenges such as analysing data from largely unknown, potentially noisy and lossy sensor signals, fusion of highly asynchronous and heterogenous information, learning from little data, “green” efficient processing, or coping with uncertainty. For protection of our health data, but shared benefit from each other’s data, further considerations touch upon adversarial attacks and federated learning. Tomorrow’s ambient health intelligence may offer real-time and earlier diagnosis, and personalised therapy for all, anytime, anywhere, but it comes with great responsibility.

It is a great pleasure to present this invited talk by Ivana Isgum from the University of Amsterdam on her great research in the field of Machine Learning and Medical Imaging:
Title: Deep learning for automatic detection of cardiovascular disease in CT and MR exams
Prof. Dr. Ivana Išgum, UMC Amsterdam, University of Amsterdam
Abstract: Deep learning has revolutionized many fields including medical imaging. Routinely acquired cardiac images provide important information for the diagnosis of cardiac disease, and image-guided therapy and intervention. In this presentation, I will show recent development of the AI methods for automatic analysis of cardiac CT and MR exams in my group. Cardiac CT allows visualization of coronary arteries. Hence, I will present our work for a fully automatic analysis of the coronary artery morphology in CT exams. Moreover, to extend the utilization potential of the CT exams, we are developing methods for quantification of cardiac function through analysis of cardiac chambers in 4D CT. Unlike CT, MR is routinely used for the quantification of cardiac function. Therefore, I will present the methods we are developing for the automation of this process. Finally, I will briefly show how we address the interpretability of the automatic decision making, quantification of uncertainty, and other issues related to the implementation of automatic AI methods.
Biography: Ivana Išgum is University Professor of AI and Medical Imaging at the Amsterdam University Medical Center, University of Amsterdam. In fall 2018 she started as Scientific Lead of the company Quantib-U. Ivana Išgum graduated in Mathematics at the University of Zagreb, Croatia in 1999. She obtained her PhD degree at the Image Sciences Institute in 2007 with a thesis titled ‘Computer-aided detection and quantification of arterial calcifications with CT’. She was a Postdoc at the Laboratory for Clinical and Experimental Image Processing in Leiden University Medical Center, and subsequently Assistant and Associate Professor at UMC Utrecht where she was leading Quantitative Medical Image Analysis (QIA) group at the Image Sciences Institute. In 2019 Ivana was appointed Full Professor and moved with her group to University of Amsterdam. Her group is focusing on the development of algorithms for quantitative analysis of medical images to enable automatic patient risk profiling, diagnosis and prognosis using AI techniques. Ivana Išgum is the recipient of several large grants, has presented extensively in medical image conferences and published in scientific peer-reviewed journals.

It’s a great pleasure to welcome Prof. Dr. Jong Chul Ye from KAIST for a presentation to our lab!
Abstract: Although deep neural networks have been widely studied for medical imaging applications, most of them are supervised learning framework that requires matched label data. Unfortunately, in many medical imaging applications, high-quality label data is often difficult to obtain, so the need for unsupervised learning is increasing. In this talk, I will mainly focus on unsupervised learning in medical image reconstruction problems such as low-dose X-ray CT, accelerated MRI, ultrasound, optics, etc., when the matched target data are not available. In particular, we introduce a recent advance of generative models, in particular optimal transport-driven CycleGAN framework, which has a strong mathematical background and can be readily incorporated with the imaging physics. The use of optimal transport driven cycleGAN for low-dose X-ray CT, CT metal artifact removal, accelerated MRI, MR motion artifact removal, ultrasound imaging artifact removal, etc., which have been pioneered by our lab, will be also introduced.

It’s a great pleasure to welcome Prof. Dr. Markus Haltmeier for an invited talk on Image Reconstruction.
Abstract: Inverse problems consist of finding accurate approximations for the unknown. Unknown x from noisy data y = A (x) + b, where A is the so-called forward operator, b represents the noise (data perturbation) and y are given noisy data. The characteristic property of inverse problems is their ill-posedness, which means that A(x) = y has no unique solution or the solution depends unstably on the given data. To obtain stable and accurate solutions, regularisation methods incorporate additional available information about the unknown and the noise. In this talk, we review classical frame-based analysis and synthesis regularisation. We then present recent extensions that use neural networks as nonlinear synthesis and analysis operators. A mathematical analysis is given, possible training strategies are discussed and connections to related work are presented. This talk is based on:

It’s a great pleasure to announce Dr. Xin Lai from Erlangen’s University Clinic!
Abstract: Dendritic cells (DCs) are professional antigen-presenting cells that induce and regulate adaptive immunity by presenting antigens to T cells. Due to their coordinative role in adaptive immune responses, DCs have been used as cell-based therapeutic vaccination against cancer. The capacity of DCs to induce a therapeutic immune response can be enhanced by re-wiring of cellular signalling pathways with microRNAs (miRNAs).
Since the activation and maturation of DCs is controlled by an interconnected signalling network, we deploy an approach that combines RNA sequencing data and systems biology methods to delineate miRNA-based strategies that enhance DC-elicited immune responses.
Through RNA sequencing of IKKβ-matured DCs that are currently being tested in a clinical trial on therapeutic anti-cancer vaccination, we identified 44 differentially expressed miRNAs. According to a network analysis, most of these miRNAs regulate targets that are linked to immune pathways, such as cytokine and interleukin signalling. We employed a network topology-oriented scoring model to rank the miRNAs, analysed their impact on immunogenic potency of DCs, and identified dozens of promising miRNA candidates, with miR-15a and miR-16 as the top ones. The results of our analysis are presented in a database that constitutes a tool to identify DC-relevant miRNA-gene interactions with therapeutic potential (www.synmirapy.net/dc-optimization).
Our approach enables the systematic analysis and identification of functional miRNA-gene interactions that can be experimentally tested for improving DC immunogenic potency.
Short Bio: Xin Lai is a research fellow at University of Erlangen-Nürnberg. He obtained his doctorate in systems biology at University of Rostock in 2013. His research makes use of methods from biomathematics and bioinformatics to analyze biological data. He developed and proposed a systems biology approach to identify therapeutic microRNAs in cancer. His interests broadened into human genomics, network biology, and computational modelling through lecturing and from tutoring engineer and medical students from primary research papers. More than 10-year collaboration with experimental researchers led him to realize the importance of a systematic and integrative overview of biomedical research. As a researcher, he is now using this perspective to conduct research in medical systems biology. In addition, he is a father with a great passion for basketball, photography, and cooking.

It’s a great pleasure to announce Dr. Julio Vera Gonzalez from Erlangen’s University Clinic!
Abstract: Multifactorial diseases like cancer are not controlled by single genes, but instead by dense networks of interacting genes, proteins and RNAs. Comprehensive reconstruction and analysis of these networks requires quantitative data and network analysis algorithms.
In addition, these networks are enriched in feedback and feedforward loops that make their dynamics complex and highly non-linear. One can use different types of computational models to simulate the dynamics of the networks. The information obtained can be used to delineate gene signatures that predict for cancer aggressiveness or resistance to therapy.

Title: “Ethical ML: mind the assumptions”
Speaker: Prof. Dr. Isabel Valera (Saarland University & Max Planck Institute for Software Systems)
Website: https://ivaleram.github.io/
Abstract: As automated data analysis supplements and even replaces human supervision in consequential decision-making (e.g., pretrial bail and loan approval), there are growing concerns from civil organizations, governments, and researchers about potential unfairness and lack of transparency of these algorithmic systems. To address these concerns, the emerging field of ethical machine learning has focused on proposing definitions and mechanisms to ensure the fairness and explicability of the outcomes of these systems. However, as we will discuss in this work, existing solutions are still far from being perfect and encounter significant technical challenges. Specifically, I will show that, in order for ethical ML, it is essential to have a holistic view of the system, starting from the data collection process before training, all the way to the deployment of the system in the real-world. Wrong technical assumptions may indeed come at a high social cost.As an example, I will first focus on my recent work on both fair algorithmic decision-making, and algorithmic recourse. In particular, I will show that algorithms may indeed amply the existing unfairness level in the data, if their assumptions do not hold in practice. Then, I will focus on algorithmic recourse, which aims to guide individuals affected by an algorithmic decision system on how to achieve the desired outcome. In this context, I will discuss the inherent limitations of counterfactual explanations, and argue for a shift of paradigm from recourse via nearest counterfactual explanations to recourse through interventions, which directly accounts for the underlying causal structure in the data. Finally, we will then discuss how to achieve recourse in practice when only limited causal information is available.

Dr. Essam Rashed has been working in many fields of medical image processing. Therefore, it’s a great pleasure to host him as a virtual guest in our lab!
Abstract: Transcranial magnetic stimulation (TMS) is a commonly used clinical procedure for neurophysiological characterization. Personalized TMS requires a pipeline for individual head model generation to provide target-specific brain stimulation. This process includes intensive segmentation of several head tissues based on MRI data, which has significant potential for segmentation error, especially for low-contrast tissues. Uniform electrical dielectric properties are assigned to each tissue in the model, which is an unrealistic assumption based on conventional volume conductor modeling. In this talk, I will briefly highlight this problem and discuss new approaches for fast and automatic estimation of the dielectric properties in the human head models without anatomical segmentation.
Short Bio: Essam Rashed received his B.Sc. in Scientific Computing in 1998 and M.Sc. in Computer Science in 2002, both from Suez Canal University, Ismailia, Egypt. He received Ph.D. (Eng.) in Computer Science from the University of Tsukuba, Tsukuba, Japan in 2010. From 2010 to 2012, he was a Research Fellow of the Japan Society for the Promotion of Science (JSPS) at the University of Tsukuba, Japan. He served as Assistant Professor of Computer Science at the Department of Mathematics, Faculty of Science, Suez Canal University from 2012 to 2016. Since then, he was promoted to Associate Professor at Suez Canal University, Egypt and worked at Faculty of Informatics and Computer Science, The British University in Egypt on Secondment. Currently, he is a Research Associate Professor at Nagoya Institute of Technology. His research interests include medical image processing, data analysis and visualization, deep learning and pattern recognition. Dr. Rashed is IEEE Senior Member and Associate Editor of IEEE Access. He is a recipient of the Egyptian National Doctoral Scholarship (2006), JSPS postdoctoral fellowship (2010), JAMIT best presentation award (2008 & 2012), and Chairman Award, Department of Computer Science, University of Tsukuba (2010). He participated as a PI and CoI for several external funded projects.

It would have been great to welcome Emil to the Bergkirchweih this year. Unfortunately, the festival was cancelled. Yet, we still have the pleasure to have Emil virtually here in Erlangen!
Abstract: This talk examines the claim made in the literature that ill-posed inverse problems associated with image reconstruction in computed tomography (CT) can be solved with a convolutional neural network (CNN). To lay the groundwork, a brief overview of inverse problems will be given including a discussion on what makes an inverse problem ill-posed and what constitutes its solution. Examples of how inverse problem investigations play a role in CT image reconstruction will be presented in order to appreciate the value of the generalizable knowledge gained in such studies. Having set the stage, the talk will the discuss the evidence that deep-learning with convolutional neural networks solve the CT inverse problem. Finally, I will cover our own investigation into the use of CNNs to solve the sparse-view CT inverse problem in the context of a breast CT simulation.

Dr. Mike Kestemont is a long-term collaborator of FAU with respect to Digital Humanities. We finally managed to get him for an invited presentation on his latest research:
Abstract: In this talk, I will report on recent advances in applying quantitative methods from ecology to data from the cultural heritage domain, in particular historic literature. With biodiversity under global threat, ecologists rely on unseen species models to monitor species richness and account for the unobserved species in a sample. I hope to demonstrate that similar bias mitigation strategies are useful in the historic study of culture, which is prone to survivorship bias in the face of the incomplete survival of sources. In collaborative work, we have applied established estimators from ecology to model the loss of chivalric narrative fiction from medieval Europe, including the well-known courtly romances about King Arthur. In more recent work, we explore to which other kinds of heritage data these methods can be applied, such as the number of premodern authors that were not saved from oblivion. This work has been carried out with multiple co-authors, in particular dr. Folgert Karsdorp (Meertens Institute Amsterdam), who will be duly credited in the talk.
Short Bio: Mike Kestemont, PhD, is associate research professor in the department of Literature at the University of Antwerp (Belgium). He specializes in computational text analysis for the Computational Humanities. His work has a strong focus on historic literature and his previous research has covered a wide range of topics in literary history, including classical, medieval, early modern and modernist texts. Together with Folgert Karsdorp and Allen Riddell he has just published a textbook on data science for the Humanities with Princeton University Press. Mike recently took up an interest in ecology and how its quantitative methods can be meaningfully applied in the study of culture. Mike lives in Brussels (www.mike-kestemont.org), tweets in English (@Mike_Kestemont) and codes in Python (https://github.com/mikekestemont).

It is a great pleasure to announce Timothy Odonga as speaker at our lab! Timothy will present his latest research on fairness of classifiers that was already featured on MICCAI and NeurIPS Fair ML for Health.
Abstract: Recent advances in computer vision have led to breakthroughs in the development of automated skin image analysis. However, no attempt has been made to evaluate the consistency in performance across populations with varying skin tones. In this paper, we present an approach to estimate skin tone in skin disease benchmark datasets and investigate whether model performance is dependent on this measure. Specifically, we use Individual Typology Angle (ITA) to approximate skin tone in dermatology datasets. We look at the distribution of ITA values to better understand skin color representation in two benchmark datasets: 1) the ISIC 2018 Challenge dataset, a collection of dermoscopic images of skin lesions for the detection of skin cancer, and 2) the SD-198 dataset, a collection of clinical images capturing a wide variety of skin diseases. To estimate ITA, we first develop segmentation models to isolate non diseased areas of skin. We find that the majority of the data in the two datasets have ITA values between 34.5 and 48, which are associated with lighter skin, and is consistent with under-representation of darker skinned populations in these datasets. We also find no measurable correlation between accuracy of machine learning models and ITA values, though more comprehensive data is needed for further validation.
Short Bio: Timothy holds a master’s degree in Electrical and Computer Engineering from Carnegie Mellon University, and two bachelor’s degrees in Physics and Electrical Engineering from Gordon College and the University of Southern California, respectively. He has experience working on research projects in machine learning at CMU and IBM Research. During his time at IBM Research, he was an IBM Great Minds scholar and an AI for Social Good fellow as he worked on a project on AI Fairness in dermatology. The research papers from this work were accepted and published in the MICCAI 2020 conference, and the NeurIPS Fair ML for Health Workshop in 2019. His research interests include machine learning for healthcare focusing on topics like fairness, explainability, and causality

Prof. Dr. Schnabel has been shaping the world of medical imaging like few other persons. It’s great pleasure to have her here in Erlangen for an invited talk!
Abstract: Medical imaging spans the entire process from acquisition, reconstruction, and quality control to image segmentation, classification, and interpretation. Recent years have increasingly seen the use of machine learning and deep learning architectures along the entire imaging pipeline, providing innovative end-to-end learning solutions that can operate directly on the imaging sensor during image acquisition, for online interpretation by the clinician. In this talk I will focus on some recently developed “smart” medical imaging approaches applied to imaging problems in three major healthcare challenges: cancer, cardiovascular disease, and premature birth. I will specifically focus on physically and biologically realistic data augmentation, as well as real-time applications of our methods during scan-time, showing promise in image interpretation tasks that are typically only performed further down-stream, but that can equally contribute to achieving better image quality and more robust extraction of clinically relevant information.
Short Bio: Julia Schnabel graduated with an MSc in Computer Science at Technical University of Berlin (1993) and a PhD in Computer Science at University College London (1998), and subsequently held post-doctoral positions at University College London, King’s College London and University Medical Center Utrecht, before becoming first Associate Professor (2007) and then Full Professor (2014) of Engineering Science at the University of Oxford. In 2015 she joined King’s College London as Chair in Computational Imaging. Julia’s research focusses on machine/deep learning, complex motion modelling, as well as multi-modality and quantitative imaging for a range of medical imaging applications. She is serving on the Editorial Board of Medical Image Analysis, is Associate Editor for IEEE Transactions on Medical Imaging and IEEE Transactions on Biomedical Engineering, and has recently founded the new free open-access Journal of Machine Learning for Biomedical Imaging (melba-journal.org).

Florian Willomitzer is former PhD graduate of FAU and is now back to report on his latest exciting research that he conducted during his time as research assistant professor at Northwestern University.
Abstract: In recent years, the introduction of modern computer vision algorithms has led to new and exciting developments in imaging sciences, such as lidar 3d mapping for autonomous driving or medical imaging and displaying tools that assist doctors in diagnosis and therapy. In light of the seemingly limitless opportunities of these developments, the knowledge about fundamental limits has become even more important: By knowing that our imaging device already operates at the physical limit (e.g., of resolution), we can avoid unnecessary investments in better hardware, such as faster detectors, better optics, or cameras with higher pixel resolution. Moreover, limits often appear as uncertainty products, making it possible to optimize our measurement towards a specific quantity (e.g., speed) by trading in information less critical for the respective application. Although the imaging device is essential in this optimization, the central role is assumed by the illumination, which serves as an encoder of the desired information.
In this talk, I will discuss the virtue of limits and merit of illumination modalities in computational 3D imaging systems using examples of my research. Among other projects, I will introduce a novel method to image hidden objects through scattering media or around corners and the ‘single-shot 3D video camera’ – a highly precise 3D sensor for the dense measurement of fast macroscopic live scenes.
Short Bio: Florian Willomitzer is a Research Assistant Professor at Northwestern University, USA. He graduated from the University of Erlangen-Nuremberg, Germany, where he received his Ph.D. degree with honors (‘summa cum laude’) in 2017. During his doctoral studies Florian investigated physical and information theoretical limits of optical 3D-sensing and implemented sensors that operate close to these limits.
At Northwestern University, Florian and his students develop novel techniques to overcome traditional resolution limitations and dynamic range restrictions in 3D and 2D imaging. Moreover, Florian’s research is focused on new methods to image hidden objects through scattering media or around corners, high-resolution holographic displays, and the implementation of high precision metrology methods in low-cost mobile handheld devices.
Florian is currently Chair of the OSA COSI conference and has served as reviewer for OSA, IEEE, SPIE, and the Nature Portfolio. His Ph.D. thesis was awarded with the Springer Theses Award for Outstanding Ph.D. Research.

It’s a great pleasure to welcome Udaranga Wickramasinghe from EPFL, Lausanne, Switzerland at our lab for an invited talk!
Abstract: CNN-based volumetric methods that label individual voxels dominate the field of biomedical image segmentation. However, 3D surface representations of the segmented structures are often required for tasks like shape analysis. They can be obtained by post-processing the labeled volumes which typically introduces artifacts and prevents end-to-end training. In this talk, I introduce Voxel2Mesh, a novel architecture that goes from 3D image volumes to 3D surfaces directly without any post-processing and with better accuracy than current methods when using smaller training datasets. I will discuss in detail about the motivation, design choices, strengths and limitations of the architecture. I will also discuss how this can help to accelerate the adoption of deep learning techniques for shape analysis in medical imaging.
Short Bio: Udaranga Wickramasinghe is a PhD student at CVLAB – EPFL advised by Prof. Pascal Fua. His research focuses on 3D surface extraction from volumetric images and ways to introduce prior knowledge into deep neural networks. Prior to joining CVLAB, he completed his master’s degree in Computer Science at EPFL, Switzerland in 2017 and his bachelor’s degree in Electronics and Telecommunication Engineering at University of Moratuwa, Sri Lanka in 2014.

We welcome Dr. Anton Batliner back to the Pattern Recognition Lab. In his presentation, he will inform us on the problems of worshipping the excessive use of significance testing.
Abstract: Null Hypothesis Testing (NHT) with p-values as decisive criteria has been criticized from its very beginning, back in the last century. The American Statistical Association published two position papers in 2016 and 2019, questioning its role in science and envisioning a “World Beyond p < 0.05“. Yet, NHT as ritual prevails until today. We will describe the shortcomings of NHT and sketch alternative ways of evaluating results such as explorative statistics, bootstrapping, and confidence intervals.
Short Bio: ANTON BATLINER received his doctor degree in Phonetics in 1978 at LMU Munich. He has been with the Institute for Nordic Languages and the Institute for German Philology, both at LMU Munich, the IMS at Stuttgart University, the Pattern Recognition Lab at FAU Erlangen, the Institute for Human-Machine Communication at TUM, the Chair of Complex and Intelligent Systems, University of Passau, and the Chair of Embedded Intelligence for Health Care and Wellbeing at University of Augsburg. He is co-editor/author of two books and author/co-author of more than 300 technical articles, with an h-index of 48 and >11000 citations. His main research interests are all (cross-linguistic) aspects of prosody and (computational) paralinguistics. He repeatedly served as co-organiser for Workshops/Sessions/Challenges on emotion and other paralinguistic events at LREC, ICPhS, Speech Prosody, and Interspeech. He was guest editor for AHCI, CSL, and Speech Communication, Associated Editor for the IEEE Transactions on Affective Computing, as well as reviewer for numerous leading journals, conferences, and workshops.

Alicia Fornes is performing ground-breaking research in hand-written document analysis at the Computer Vision Center, Barcelona, Spain. So, it’s a great pleasure to welcome her to Beyond the Patterns!
Abstract: Lately, document image analysis and recognition systems have become fundamental for recognizing, searching and extracting information from historical manuscripts, easing the access and indexing of our cultural heritage. However, and even with the recent advances in deep learning, historical handwritten documents are difficult due to the variability in the handwriting styles and the few available labelled data. For this reason, synthetic data generation, domain adaptation or few-shot learning techniques have been proposed for alleviating those problems.

It’s a great pleasure to announce our next guest in our invited lecture series “Beyond the Patterns”.
Abstract: European competition law prohibits the coordination of economic decisions among market participants, esp. price fixing. Information exchange or even unilateral advance communication of prices may amount to such an illegal collusion. The lecture gives a brief introduction to the rules against coordinated behavior and explains the difference between a coordinated behavior based on information exchange and a legal parallel behavior based on available information.

We welcome Prof. Dr. Daniel Cremers as an invited speaker to our lab next week and are looking forward to his presentation.
Abstract: While neural networks have swept the field of computer vision and replaced classical methods in most areas of image analysis and beyond, extending their power to the domain of camera-based 3D reconstruction and visual SLAM remains an important open challenge. In my talk, I will discuss the problem of image-based reconstruction and visual Simultaneous Localization and Mapping (SLAM). In particular, I will advocate direct methods that recover 3D structure and camera motion directly from the intensity images. Moreover, I will discuss how the performance of visual SLAM methods can be drastically enhanced using the predictive power of deep networks.

Our invited speaker in this video is Luis Pineda from Facebook AI Research!
Abstract: Deep learning approaches have recently shown great promise in accelerating magnetic resonance image (MRI) acquisition. The majority of existing work have focused on designing better reconstruction models given a pre-determined acquisition trajectory, ignoring the question of trajectory optimization. In this paper, we focus on learning acquisition trajectories given a fixed image reconstruction model. We formulate the problem as a sequential decision process and propose the use of reinforcement learning to solve it. Experiments on a large scale public MRI dataset of knees show that our proposed models significantly outperform the state-of-the-art in active MRI acquisition, over a large range of acceleration factors.
Bio: Luis Pineda is a researcher at Facebook AI Research in Montreal. He obtained his PhD from University of Massachusetts Amherst in 2018, advised by Prof. Shlomo Zilberstein; during his PhD, he focused on developing heuristic search algorithms for probabilistic planning and their applications to robotics problems. At FAIR, his focus has been on studying deep reinforcement learning and its applications. His recent work includes exploring the use of deep RL for active MRI acquisition, and developing novel RL-based methods for multi-agent collaboration in Hanabi.

It’s a great pleasure to welcome Petar Velikovi from Deep Mind to our Lab!
Abstract: The last decade has witnessed an experimental revolution in data science and machine learning, epitomised by deep learning methods. Indeed, many high-dimensional learning tasks previously thought to be beyond reach –such as computer vision, playing Go, or protein folding – are in fact feasible with appropriate computational scale. Remarkably, the essence of deep learning is built from two simple algorithmic principles: first, the notion of representation or feature learning, whereby adapted, often hierarchical, features capture the appropriate notion of regularity for each task, and second, learning by local gradient-descent type methods, typically implemented as backpropagation.
While learning generic functions in high dimensions is a cursed estimation problem, most tasks of interest are not generic, and come with essential pre-defined regularities arising from the underlying low-dimensionality and structure of the physical world. This talk is concerned with exposing these regularities through unified geometric principles that can be applied throughout a wide spectrum of applications.
Such a ‘geometric unification’ endeavour in the spirit of Felix Klein’s Erlangen Program serves a dual purpose: on one hand, it provides a common mathematical framework to study the most successful neural network architectures, such as CNNs, RNNs, GNNs, and Transformers. On the other hand, it gives a constructive procedure to incorporate prior physical knowledge into neural architectures and provide principled way to build future architectures yet to be invented.
Bio:Petar Velikovi is a Senior Research Scientist at DeepMind. He holds a PhD in Computer Science from the University of Cambridge (Trinity College), obtained under the supervision of Pietro Liò. His research interests involve devising neural network architectures that operate on nontrivially structured data (such as graphs), and their applications in algorithmic reasoning and computational biology. He has published relevant research in these areas at both machine learning venues (NeurIPS, ICLR, ICML-W) and biomedical venues and journals (Bioinformatics, PLOS One, JCB, PervasiveHealth). In particular, he is the first author of Graph Attention Networks—a popular convolutional layer for graphs—and Deep Graph Infomax—a scalable local/global unsupervised learning pipeline for graphs (featured in ZDNet). Further, his research has been used in substantially improving the travel-time predictions in Google Maps (covered by outlets including the CNBC, Endgadget, VentureBeat, CNET, the Verge and ZDNet).

The famous author of the nnU-Net Paper is giving some insights on his most recent discoveries on medical image segmentation at our lab in the next week!
Abstract: Biomedical imaging is a driver of scientific discovery and a core component of medical care and is being stimulated by the field of deep learning. While semantic segmentation algorithms enable image analysis and quantification in many applications, the design of respective specialized solutions is non-trivial and highly dependent on dataset properties and hardware conditions. We developed nnU-Net, a deep learning-based segmentation method that automatically configures itself, including preprocessing, network architecture, training and post-processing for any new task. The key design choices in this process are modeled as a set of fixed parameters, interdependent rules and empirical decisions. Without manual intervention, nnU-Net surpasses most existing approaches, including highly specialized solutions on 23 public datasets used in international biomedical segmentation competitions. We make nnU-Net publicly available as an out-of-the-box tool, rendering state-of-the-art segmentation accessible to a broad audience by requiring neither expert knowledge nor computing resources beyond standard network training.

We just had the great pleasure to welcome Jinwei Zhang to our lab for a presentation on his latest research.
Abstract: A learning-based posterior distribution estimation method, Probabilistic Dipole Inversion (PDI), is proposed to solve the quantitative susceptibility mapping (QSM) inverse problem in MRI with uncertainty estimation. In PDI, a deep convolutional neural network (CNN) is used to represent the multivariate Gaussian distribution as the approximate posterior distribution of susceptibility given the input measured field. Such CNN is first trained on healthy subjects via posterior density estimation, where the training dataset contains samples from the true posterior distribution. Domain adaptations are then deployed on patient datasets with new pathologies not included in pre-training, where PDI updates the pre-trained CNN’s weights in an unsupervised fashion by minimizing the Kullback-Leibler divergence between the approximate posterior distribution represented by CNN and the true posterior distribution from the likelihood distribution of a known physical model and pre-defined prior distribution. Based on our experiments, PDI provides additional uncertainty estimation compared to the conventional MAP approach, while addressing the potential issue of the pre-trained CNN when test data deviates from training.
Short Bio: Jinwei Zhang is a Ph.D. student in Cornell MRI research lab, under the supervision of Yi Wang. The current focus of his work is to develop AI-based methods to optimize the sampling and reconstruction process of MRI, especially quantitative susceptibility mapping with multi-echo image acquisition and reconstruction. Prior to Cornell, he obtained a B.S. in physics from Sun-Yat-sen university.

It’s a great pleasure to announce an invited talk from TU Munich by Roger David Soberanis Mukul in Beyond the Patterns.
Abstract: Organ segmentation is an essential pre-processing step in different computer-assisted tasks, and currently, deep convolutional neural networks lead the state-of-the-art. However, the nature of the medical images can lead to errors in the segmentation process, generating false negative and false positive regions in the results. Recent works have shown that the uncertainty of deep convolutional neural networks (CNN) can provide helpful insights about potential errors in the network’s predictions. Inspired by these works and the recent graph convolutional networks, we propose using the CNN’s uncertainty to formulate the refinement process as a semi-supervised graph learning problem. To validate our method, we refine the predictions of a 2D U-Net, trained on the NIH pancreas dataset and the spleen dataset of the medical segmentation decathlon. Finally, we perform a sensitivity analysis on the parameters of our proposal.
Short Bio: Roger Soberanis is a PhD student at the Chair for Computer Aided Medical Procedures and Augmented Reality, Technical University of Munich. He studied a bachelor’s in computer engineering and a master’s in computer science at the Mathematics faculty of the Autonomous University of Yucatan, Mexico. His work focus on deep convolutional and graph-convolutional networks for medical applications, with a particular interest in medical image segmentation.

It’s a great pleasure to welcome Raghav Selvan from the University of Copenhagen at our lab!
Abstract: Quantum Tensor Networks (QTNs) provide efficient approximations of operations involving high dimensional tensors and have been extensively used in modeling quantum many-body systems and also compressing large neural networks. More recently, supervised learning has been attempted with tensor networks, and has primarily focused on classification of 1D signals and small images. In this talk, we will look at two formulations of QTN-based models for 2D & 3D medical image classification and 2D medical image segmentation. Both the classification and segmentation models use the matrix product state (MPS) tensor network under the hood, which efficiently learns linear decision rules in high dimensional spaces. These QTN models are fully linear, end-to-end trainable using backpropagation, and have a lower GPU memory footprint than convolutional neural networks (CNN). We show competitive performance compared to relevant CNN baselines on multiple datasets for classification and segmentation tasks while presenting interesting connections to other existing supervised learning methods.

It’s great pleasure to welcome Prof. Dr. Tobias Reichenbach to FAU as a new professor after running a successful lab at Imperial College London!
Abstract: Understanding speech in noisy backgrounds requires selective attention to a particular speaker. Humans excel at this challenging task, while current speech recognition technology still struggles when background noise is loud. The neural mechanisms by which we process speech remain, however, poorly understood, not least due to the complexity of natural speech. Here we describe recent progress obtained through applying machine-learning to neuroimaging data of humans listening to speech in different types of background noise. In particular, we develop statistical models to relate characteristic features of speech such as pitch, amplitude fluctuations and linguistic surprisal to neural measurements. We find neural correlates of speech processing both at the subcortical level, related to the pitch, as well as at the cortical level, related to amplitude fluctuations and linguistic structures. We also show that some of these measures allow to diagnose disorders of consciousness. Our findings may be applied in smart hearing aids that automatically adjust speech processing to assist a user, as well as in the diagnosis of brain disorders.

It’s a great pleasure to welcome Prof. Amy Kuceyeski at our lab for an invited presentation!
Abstract: The recent explosion of machine learning literature has centered largely around Artificial Neural Networks (ANNs). These networks, originally inspired by biological neural networks – specifically, how the human brain processes visual information (Rosenblatt et al., 1958) – have proved remarkably useful for classification or regression problems of many types. Meanwhile, in the field of neuroscience, researchers have incorporated ANNs into “encoding models” that predict neural responses to visual stimuli and, furthermore, have been shown to reflect structure and function of the visual processing pathway. This observation has led to speculation that primate ventral visual stream may have evolved to be an optimal system for object recognition/detection in the same way that ANNs are identifying optimal computational architectures. Here, we introduce NeuroGen, a novel encoding/generative model architecture designed to synthesize realistic images predicted to maximize or minimize activation in pre-selected regions of the human visual cortex. We then apply this framework as a discovery architecture to amplify differences in regional and individual brain response patterns to visual stimuli, and, furthermore, use it to generate synthetic images predicted to achieve levels of activation above and beyond what is achievable with natural images. If it can be shown with future work that the synthetic images actually produce the desired target responses, this approach could be used to perform macro-scale, non-invasive neuronal population control in humans.
Short Bio: Amy Kuceyeski is an Associate Professor in the Department of Radiology at Weill Cornell Medicine and in Computational Biology at Cornell University. For the past decade, Amy has been interested in understanding how the human brain works in order to better diagnose, prognose and treat neurological disease and injury. The CoCo lab’s main focus is on using quantitative methods, including machine learning, applied to multi-modal neuroimaging data to map brain-behavior relationships. The lab’s overall goal is to develop individualized therapies that can boost natural recovery mechanisms and support recovery after neurological disease or injury.

It’s a great pleasure to welcome FAU Alumnus Nils Thuerey to our lab for an invited presentation!
Abstract:
In this talk, I will focus on the possibilities that arise from recent advances in the area of deep learning for physical simulations. In this context, especially the Navier-Stokes equations represent an interesting and challenging advection-diffusion PDE that poses a variety of challenges for deep learning methods.
In particular, I will focus on differentiable physics solvers within the larger field of differentiable programming. Differentiable solvers are very powerful tools to guide deep learning processes and support finding desirable solutions. The existing numerical methods for efficient solvers can be leveraged within learning tasks to provide crucial information in the form of reliable gradients to update the weights of a neural network. Interestingly, it turns out to be beneficial to combine supervised and physics-based approaches. The former poses a much simpler learning task by providing explicit reference data that is typically pre-computed. Physics-based learning on the other hand can provide gradients for a larger space of states that are only encountered during training runs. Here, differentiable solvers are particularly powerful to, e.g., provide neural networks with feedback about how inferred solutions influence the long-term behavior of a physical model.
I will demonstrate this concept with several examples from learning to reduce numerical errors, over long-term planning and control, to generalization. I will conclude by discussing current limitations and by giving an outlook about promising future directions.
Short Bio: Nils Thuerey is an Associate-Professor at the Technical University of Munich (TUM). He focuses on deep-learning methods for physical systems, with an emphasis on fluid flow problems. Beyond latent-space simulation algorithms and generative models, he’s currently especially interested in learning algorithms powered by differentiable solvers.

We are very proud to welcome Gitta Kutyniok from LMU Munich to our lab!
Abstract: One or maybe the main reason for the impressive success of deep neural networks in both public life and science is their amazing generalization ability, namely their performance on unseen data. However, this phenomenon is still to a large extent a mystery.
In this talk, we will provide an introduction to this problem and discuss some recent advances. We will then focus on graph convolutional neural networks and show how to unravel part of the mystery in this situation completely.
Short Bio: Kutyniok was educated in Detmold, and in 1996 earned a diploma in mathematics and computer science at Paderborn University. She completed her doctorate (Dr. rer. nat.) at Paderborn in 2000. Her dissertation, Time-Frequency Analysis on Locally Compact Groups, was supervised by Eberhard Kaniuth.
From 2000 to 2008 she held short-term positions at Paderborn University, the Georgia Institute of Technology, the University of Giessen, Washington University in St. Louis, Princeton University, Stanford University, and Yale University. In 2006 she earned her habilitation in Giessen, in 2008 she became a full professor at Osnabrück University, and in 2011 she was given the Einstein Chair at the Technical University of Berlin. In 2018 she added courtesy affiliations with computer science and electrical engineering at TU Berlin and an adjunct faculty position at the University of Tromsø..

Abstract: Artificial Intelligence (AI) is changing many fields across science and across our society. In this talk, we will discuss how AI is and will change medicine and healthcare, in particular in the field of radiology. In particular, I will focus on how AI can support the early detection of diseases in medical imaging as well as help with improved diagnosis and personalised therapies. I will a.so describe how deep learning can be used for the reconstruction of medical images from undersampled data, image also super-resolution, image segmentation and image classification in the context of cardiac, fetal and neuroimaging. Furthermore, we will discuss how AI solutions can be privacy-preserving while also providing trustworthy and explainable solutions for clinicians. Finally, I will discuss future developments and challenges for AI in radiology and medicine more generally.

It’s a great pleasure to welcome Jana Dambrogio from MIT and Daniel Smith from King’s College London at our lab!
Abstract: Before the invention of the gummed envelope in the 1830s, almost all letters were sent using letterlocking, the practice of folding and securing a writing surface to become its own envelope. Based on 20 years research into 250,000 letters, this talk and workshop will present our main findings, including information about the letter we “virtually unfolded” in a recent
Nature Communications article: https://www.nature.com/articles/s41467-021-21326-w.
There will also be an opportunity to do some letterlocking yourself! Please bring some paper (printer paper is fine), scissors, some stickers or sticky tape (kids’ stickers are more fun!), and some sewing thread. You may also wish to check out letterlocking.org and our YouTube channel: https://www.youtube.com/channel/UCNPZ-f_IWDLz2S1hO027hRQ.
Short Bios: Jana Dambrogio is a conservator, researcher, educator, letterlocker, and artist who specializes in developing freely accessible resources and treatment techniques to conserve the integrity of material culture and the secrets they contain. At present, she is Conservator at the Massachusetts Institute of Technology (MIT) Curation and Preservation Services.
Dr. Daniel Smith is Lecturer in Early Modern English Literature at Kings’s College London, UK and performs award winning research which won the John Donne Society Distinguished Publication Award in 2011 and the University English Book Prize in 2016.
G.R. Davis: Professor of 3D x-ray imaging at Queen Mary, University of London, and lead for Imaging Sciences in the Centre for Oral Bioengineering, which includes electron microscopy, X-ray imaging, and facial scanning.

I am very glad to announce Adrian Dalca as an invited speaker at our lab!
Abstract: Image registration is fundamental to many tasks in image analysis. Classical image registration methods have undergone decades of technical development, but are often prohibitively slow since they solve an optimization problem for each 3D image pair. In this talk, I will introduce various models that leverage learning paradigms to enable deformable medical image registration more accurately and substantially faster than traditional methods, crucially enabling new research directions and applications. Based on these models I will discuss a learning framework for building deformable templates, which play a fundamental role in these analyses. This learning approach to template construction can yield a new class of on-demand conditional templates, enabling new analysis. I will also present recent or ongoing models, such as modality-invariant learning-based registration methods that work on unseen test-time contrasts, and hyperparameter-agnostic learning for image registration that removes the need to train different models for different hyperparameters.
Short Bio: Adrian V. Dalca is Assistant Professor at Harvard Medical School, and research scientist at the Massachusetts Institute of Technology. He obtained his PhD from CSAIL, MIT, and his research focuses on probabilistic models and machine learning techniques to capture relationships between medical images, clinical diagnoses, and other complex medical data. His work spans medical image analysis, computer vision, machine learning and computational biology. He received his BS and MS in Computer Science from the University of Toronto.
