Better Simulations for Validating Causal Discovery with the DAG-Adaptation of the Onion Method

no code implementations21 May 2024 Bryan Andrews, Erich Kummerfeld

We propose a new simulation design for generating linear models for directed acyclic graphs (DAGs): the DAG-adaptation of the Onion (DaO) method.

Causal Discovery for fMRI data: Challenges, Solutions, and a Case Study

no code implementations20 Dec 2023 Eric Rawls, Bryan Andrews, Kelvin Lim, Erich Kummerfeld

Designing studies that apply causal discovery requires navigating many researcher degrees of freedom.

Causal Discovery

Fast Scalable and Accurate Discovery of DAGs Using the Best Order Score Search and Grow-Shrink Trees

1 code implementation26 Oct 2023 Bryan Andrews, Joseph Ramsey, Ruben Sanchez-Romero, Jazmin Camchong, Erich Kummerfeld

However, the accuracy and execution time of learning algorithms generally struggle to scale to problems with hundreds of highly connected variables -- for instance, recovering brain networks from fMRI data.

Simulations evaluating resampling methods for causal discovery: ensemble performance and calibration

no code implementations4 Oct 2019 Erich Kummerfeld, Alexander Rix

One of the major hurdles preventing the field of causal discovery from having a larger impact is that it is difficult to determine when the output of a causal discovery method can be trusted in a real-world setting.

Tracking Time-varying Graphical Structure

no code implementations NeurIPS 2013 Erich Kummerfeld, David Danks

Structure learning algorithms for graphical models have focused almost exclusively on stable environments in which the underlying generative process does not change; that is, they assume that the generating model is globally stationary.
