Quantitative probing: Validating causal models using quantitative domain knowledge

2 code implementations7 Sep 2022 Daniel Grünbaum, Maike L. Stern, Elmar W. Lang

We present quantitative probing as a model-agnostic framework for validating causal models in the presence of quantitative domain knowledge.

Forecasting Brain Activity Based on Models of Spatio-Temporal Brain Dynamics: A Comparison of Graph Neural Network Architectures

no code implementations8 Dec 2021 Simon Wein, Alina Schüller, Ana Maria Tomé, Wilhelm M. Malloni, Mark W. Greenlee, Elmar W. Lang

We evaluate the performance of the GNN models on a variety of scenarios in MRI studies and also compare it to a VAR model, which is currently often used for directed functional connectivity analysis.

A Graph Neural Network Framework for Causal Inference in Brain Networks

1 code implementation14 Oct 2020 Simon Wein, Wilhelm Malloni, Ana Maria Tomé, Sebastian M. Frank, Gina-Isabelle Henze, Stefan Wüst, Mark W. Greenlee, Elmar W. Lang

Moreover, dynamic interactions between different brain regions learned by this data-driven approach can provide a multi-modal measure of causal connectivity strength.

Parameterized Reinforcement Learning for Optical System Optimization

no code implementations9 Oct 2020 Heribert Wankerl, Maike L. Stern, Ali Mahdavi, Christoph Eichler, Elmar W. Lang

Such a combination of both, discrete and continuous parameters is a challenging optimization problem that often requires a computationally expensive search for an optimal system design.

Learning intuitive physics and one-shot imitation using state-action-prediction self-organizing maps

1 code implementation3 Jul 2020 Martin Stetter, Elmar W. Lang

We demonstrate its performance on a set of several related, but different one-shot imitation tasks, which the agent flexibly solves in an active inference style.

Electricity Load Forecasting -- An Evaluation of Simple 1D-CNN Network Structures

no code implementations26 Nov 2019 Christian Lang, Florian Steinborn, Oliver Steffens, Elmar W. Lang

This paper presents a convolutional neural network (CNN) which can be used for forecasting electricity load profiles 36 hours into the future.

A constrained ICA-EMD Model for Group Level fMRI Analysis

no code implementations22 Mar 2019 Simon Wein, Ana Maria Tomé, Markus Goldhacker, Mark W. Greenlee, Elmar W. Lang

The results of the proposed workflow are then compared to those obtained by a widely used group ICA approach for fMRI analysis.
