Reconstructing Nonlinear Dynamical Systems from Multi-Modal Time Series

1 code implementation4 Nov 2021 Daniel Kramer, Philine Lou Bommer, Carlo Tombolini, Georgia Koppe, Daniel Durstewitz

Here we propose a general framework for multi-modal data integration for the purpose of nonlinear DS reconstruction and the analysis of cross-modal relations.

Inferring Dynamical Systems with Long-Range Dependencies through Line Attractor Regularization

no code implementations25 Sep 2019 Dominik Schmidt, Georgia Koppe, Max Beutelspacher, Daniel Durstewitz

Vanilla RNN with ReLU activation have a simple structure that is amenable to systematic dynamical systems analysis and interpretation, but they suffer from the exploding vs. vanishing gradients problem.

Identifying nonlinear dynamical systems via generative recurrent neural networks with applications to fMRI

no code implementations19 Feb 2019 Georgia Koppe, Hazem Toutounji, Peter Kirsch, Stefanie Lis, Daniel Durstewitz

A major tenet in theoretical neuroscience is that cognitive and behavioral processes are ultimately implemented in terms of the neural system dynamics.
