The analysis of EEG/MEG functional connectivity has become an important tool in neural research.

Granger Causality for Compressively Sensed Sparse Signals

no code yet • 23 Sep 2022

In this work, we provide a mathematical proof that structured compressed sensing matrices, specifically Circulant and Toeplitz, preserve causal relationships in the compressed signal domain, as measured by Granger Causality.

Parameter Estimation in Ill-conditioned Low-inertia Power Systems

no code yet • 9 Aug 2022

This ill-conditioning is because of converter-interfaced power systems generators' zero or small inertia contribution.

Deep Dynamic Effective Connectivity Estimation from Multivariate Time Series

no code yet • 4 Feb 2022

To bridge this gap, we developed dynamic effective connectivity estimation via neural network training (DECENNT), a novel model to learn an interpretable directed and dynamic graph induced by the downstream classification/prediction task.

no code yet • ICLR Workshop GTRL 2021

Functional connectivity (FC) studies have demonstrated the benefits of investigating the brain and its disorders through the undirected weighted graph of fMRI correlation matrix.

Improving J-divergence of brain connectivity states by graph Laplacian denoising

no code yet • 21 Dec 2020

Using our novel formulation of the J-divergence, we are able to quantify the distance between the FC networks in the motor imagery and resting states, as well as to understand the contribution of each Laplacian variable to the total J-divergence between two states.

Distance Correlation Based Brain Functional Connectivity Estimation and Non-Convex Multi-Task Learning for Developmental fMRI Studies

no code yet • 30 Sep 2020

Resting-state functional magnetic resonance imaging (rs-fMRI)-derived functional connectivity patterns have been extensively utilized to delineate global functional organization of the human brain in health, development, and neuropsychiatric disorders.
