Graph-Based Correlation Matrix Generation: A Convex Optimization Approach
Ali Fakhar, K{é}vin Polisano, Ir{è}ne Gannaz +1
This work addresses the generation of theoretical correlation matrices with prescribed sparsity patterns associated to graph structures. We propose a novel convex optimization fram…
G{é}n{é}ration de Matrices de Corr{é}lation avec des Structures de Graphe par Optimisation Convexe
Ali Fahkar, Kévin Polisano, Irène Gannaz +1
This work deals with the generation of theoretical correlation matrices with specific sparsity patterns, associated to graph structures. We present a novel approach based on convex…
Benchmarking Brain Connectivity Graph Inference: A Novel Validation Approach
Alice Chevaux, Ali Fahkar, Kévin Polisano +2
Inferring a binary connectivity graph from resting-state fMRI data for a single subject requires making several methodological choices and assumptions that can significantly affect…
