Alexander Immer

My research focuses on probabilistic machine learning and data science. Currently, I am particularly interested in approximate inference for neural networks and biomedical applications. I want to design algorithms that can incorporate prior knowledge, quantify uncertainty, and automatically select the most likely model given data. Especially in the context of neural networks, these problems remain challenging. I have previously worked on methods for time series, e.g., mobility and political data.

Amir-Hossein Karimi

I am generally interested in human behavior, how intelligence is formed in humans, and how it can be replicated in machines. As a first year PhD student, I am exploring AI methods that are interpretable and explainable, with a focus on probabilistic inference on the organization of entities, or learning compositional and causal generative processes. My research has a broad impact, potentially in three areas: (1) more adoption of machine learning methods in critical social, economic, and public health domains due to the added trust gained from explainable methods; (2) better model selection strategies that point out hazardous practices with the abundance of data, including data leakage of irrelevant factors; (3) state-of-the-art models with improved fidelity/accuracy as we are able to conduct stage-wise learning of abstract objects and concepts and then complex relationships.

My research focuses on natural language processing. I am particularly interested in designing systems that have a deep semantic and syntactic understanding of natural language, which proves useful for improving robustness to distribution shifts, interpretability and performing more complex reasoning-based tasks. To that end, I am a strong believer in neuro-symbolic methods, formal language theory and causal inference.

My research interests lie in the intersection of unsupervised structured representations learning, dynamics learning and using both for model-based reinforcement learning.

My area of research is modelling the human body, in terms of both shape and appearance, in 3D space. I am particularly interested in generative models for the human body as well as in reconstruction and modelling of clothing. Currently I am working on reconstruction and modelling of loose garments, such as skirts and dresses, as I think that is the area most lacking in current approaches for creating human avatars.

My research interests lie in the broad field of computer vision and, more specifically, are currently focused on learning structured scene representations. I'm interested to learn about ways in which humans perceive their environment and how to use these ideas in combination with deep learning methods. Moreover, I want to explore options of combining this work with other tasks like segmentation or 3D reconstruction.

I am interested in exploring forms of physical intelligence inspired by materials and mechanisms found in nature and in applying these to the design and fabrication of soft robotic systems. Particularly, my research focus lies on bioinspired actuation systems replicating the versatile performance of natural muscles - so-called HASEL (hydraulically amplified self-healing electrostatic) actuators. This new class of electrohydraulic transducers enables the creation of novel soft robotic systems with yet unmet high degrees of dexterity, agility and adaptability to their environments, making them well-suited for unstructured and dynamic tasks.

With the more and more widespread deployment of Al systems in the real world, they are likely going to have larger and larger impacts on society, including accidents, political destabilization and other negative externalities. To increase developers' accountability for negative societal impacts of their Al systems, my research focuses on a) a better theoretical understanding of these impacts, b) approaches to monitor and empirically demonstrate them, c) building tools developers can use to mitigate potential risks their Al systems might pose, and d) strategies for policymakers to align Al developers' incentives with society.

Hamza Keurti

Generally, I am interested in creating vision systems which understand visual scenes like humans do and which learn to perceive the same way children learn: through embodiment and free interaction (playing) with objects. In particular, my aim is to learn robust and predictive representations from visual scenes with the integration of efferent motor signals, in the absence of tasks. An embodied agent should learn to perceive prior to learning tasks.

Magnetically actuated continuum robots show promise for a variety of medical applications. Their high flexibility allows them to perform minimum invasive surgeries inside the human body. However, their modeling and control are particularly challenging due to nonlinear material behavior and their high degrees of freedom. During my PhD, I aim to develop intelligent learning control algorithms which allow the reliable deployment of these systems for high-precision medical interventions.

Current neural networks remain large and not fully understood. My research links network compression with model interpretability. This natural connection aims at extracting relevant information from the network while discarding the redundant parameters. This goal of reducing neural networks not only makes models faster, more practical and energy-efficient but also aims to analyze and interpret the relevant features that make up a smaller model. We look at this problem from various perspectives, ranging from probabilistic to game-theoretical approaches. My further interests lie in data generation and differential privacy.

Liang Zhang

My research focuses on the intersection between optimization and machine learning. In particular, I try to establish the theoretical guarantees of machine learning algorithms, including their convergence properties and generalization behaviors. For example, I previously worked on the convergence analyses of variance reduction methods for structured nonconvex stochastic optimization that are common in many machine learning applications such as GANs, meta-learning, and reinforcement learning. Currently, I am working on differentially private stochastic optimization due to the increasing demand for data privacy in the industry. In addition to that, I am also interested in understanding the generalization of nonconvex optimization problems.

Considering what humans are able to understand about other humans it becomes apparent that our perception goes far beyond (while surely leveraging) our geometric aspect and is able to infer semantic information such as goals, (inter)actions, intentions etc. My goal is to bridge the gap between geometry and semantics so that machines can truly understand humans and therefore more intelligently learn from, interact with and assist them.

Current state-of-the-art machine learning models often unpredictably fail when dealing with previously unseen settings, proving to be not general and robust enough for a safe deployment in life-critical applications.

My research interests lie in the area of machine learning. In particular, I am interested to enhance the understanding of algorithmic decisions in social context. In the last few years, more and more social and economic authorities have started to base their decisions on machine learning methods. Hence, it is fundamental to understand and quantify the influence such algorithmic decisions have on individuals and society as a whole. To that point, I am dealing with different concepts for causal relationships in social settings and developing suitable methods to properly infer these causal relationships from experimental and observational data.
