Robust Hierarchical Patterns for identifying MDD patients: A Multisite Study

no code implementations22 Feb 2022 Dushyant Sahoo, Mathilde Antoniades, Cynthia H. Y. Fu, Christos Davatzikos

Our model can reduce diversity and improve the predictive and generalizing capability of the components.

Learning Robust Hierarchical Patterns of Human Brain across Many fMRI Studies

no code implementations NeurIPS 2021 Dushyant Sahoo, Christos Davatzikos

We also demonstrate the improved reproducibility of the components while preserving age-related variation on a real dataset compiled from multiple sites.

Extraction of Hierarchical Functional Connectivity Components in human brain using Adversarial Learning

no code implementations20 Apr 2021 Dushyant Sahoo, Christos Davatzikos

The estimation of sparse hierarchical components reflecting patterns of the brain's functional connectivity from rsfMRI data can contribute to our understanding of the brain's functional organization, and can lead to biomarkers of diseases.

Variance Reduced Stochastic Proximal Algorithm for AUC Maximization

no code implementations8 Nov 2019 Soham Dan, Dushyant Sahoo

To combat this issue, several variance reduced methods have been proposed with faster convergence guarantees than vanilla stochastic gradient descent.

Extraction of hierarchical functional connectivity components in human brain using resting-state fMRI

no code implementations19 Jun 2019 Dushyant Sahoo, Theodore D. Satterthwaite, Christos Davatzikos

This paper provides a novel method for the extraction of hierarchical connectivity components in the human brain using resting-state fMRI.
