Learning Interpretable Hierarchical Dynamical Systems Models from Time Series Data

ICLR 2025poster

In science, we are often interested in obtaining a generative model of the underlying system dynamics from observed time series. While powerful methods for dynamical systems reconstruction (DSR) exist when data come from a single domain, how to best integrate data from multiple dynamical regimes and…

A scalable generative model for dynamical system reconstruction from neuroimaging data

NeurIPS 2024poster

Data-driven inference of the generative dynamics underlying a set of observed time series is of growing interest in machine learning and the natural sciences. In neuroscience, such methods promise to alleviate the need to handcraft models based on biophysical principles and allow to automatize the i…

Integrating Multimodal Data for Joint Generative Modeling of Complex Dynamics

ICML 2024poster

Many, if not most, systems of interest in science are naturally described as nonlinear dynamical systems. Empirically, we commonly access these systems through time series measurements. Often such time series may consist of discrete random variables rather than continuous measurements, or may be com…

Reconstructing Nonlinear Dynamical Systems from Multi-Modal Time Series

ICML 2022spotlight

Empirically observed time series in physics, biology, or medicine, are commonly generated by some underlying dynamical system (DS) which is the target of scientific interest. There is an increasing interest to harvest machine learning methods to reconstruct this latent DS in a data-driven, unsupervi…

Identifying nonlinear dynamical systems with multiple time scales and long-range dependencies

ICLR 2021spotlight

A main theoretical interest in biology and physics is to identify the nonlinear dynamical system (DS) that generated observed time series. Recurrent Neural Networks (RNN) are, in principle, powerful enough to approximate any underlying DS, but in their vanilla form suffer from the exploding vs. vani…
