Biomedical Sequence Data

The language of life is encoded as a sequence of amino acids in the form of proteins. The understanding of their properties is of fundamental interest both on the level of proteins for fundamental research as well as medical applications and on the level of peptides, i.e. protein fragments, due to applications in immunology. In particular, only for a tiny fraction of proteins is experimentally studied in enough detail such that its main functional properties are known. The work in the AML group at HHI focuses on the prediction of protein/peptide properties using the primary sequence alone, leveraging the recent advances in the field of natural language processing.

Medical Imaging Data

Medical imaging is the field of visual representation of biological structures in medicine. This makes it a very popular application for abstract algorithms. The different research methods of the AML group at HHI can be applied in an early stage such as the acquisition and reconstruction of medical images, as well in a later stage such as the diagnosis and detection of pathologies. Furthermore, the interpretable machine learning methods that we develop are of fundamental need for a transparent and safe deployment of machine learning algorithms.

Medical Time Series

Time series data constitutes a rich data modality that is highly relevant for applications in the medical domain as it includes for example electrocardiography (ECG), electrical impedance tomography (EIT), electroencephalography (EEG) but also gait data. The AML group develops algorithms for the analysis of such data with particular regard to quality criteria ranging from quantitative accuracy to interpretability and beyond.

MCMC Physics

Markov Chain Monte Carlo (MCMC) methods are the workhorses of theoretical physics and offer insights from first-principles into strongly interacting theories ranging from high-energy physics to solid-state physics. In the AML group we are exploring ML techniques to complement MCMC approaches by means of generative models and to uncover hidden structures from MCMC configurations alone.
