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.

Causal Discovery

Identification of Effective Connectivity Subregions

no code implementations8 Aug 2019 Ruben Sanchez-Romero, Joseph D. Ramsey, Kun Zhang, Clark Glymour

These algorithms allow for identification of subregions of voxels driving the connectivity between regions of interest, recovering valuable anatomical and functional information that is lost when ROIs are aggregated.

Causal Discovery from Heterogeneous/Nonstationary Data with Independent Changes

no code implementations5 Mar 2019 Biwei Huang, Kun Zhang, Jiji Zhang, Joseph Ramsey, Ruben Sanchez-Romero, Clark Glymour, Bernhard Schölkopf

In this paper, we develop a framework for causal discovery from such data, called Constraint-based causal Discovery from heterogeneous/NOnstationary Data (CD-NOD), to find causal skeleton and directions and estimate the properties of mechanism changes.

Causal Discovery

Diagnosis of Autism Spectrum Disorder by Causal Influence Strength Learned from Resting-State fMRI Data

no code implementations27 Jan 2019 Biwei Huang, Kun Zhang, Ruben Sanchez-Romero, Joseph Ramsey, Madelyn Glymour, Clark Glymour

A substantial body of researches use Pearson's correlation coefficients, mutual information, or partial correlation to investigate the differences in brain connectivities between ASD and typical controls from functional Magnetic Resonance Imaging (fMRI).
