Interpretable and Adaptive Node Classification on Heterophilic Graphs via Combinatorial Scoring and Hybrid Learning
Soroush Vahidi
Graph neural networks (GNNs) achieve strong performance on homophilic graphs but often struggle under heterophily, where adjacent nodes frequently belong to different classes. We p…

Minimum Weighted Feedback Arc Sets for Ranking from Pairwise Comparisons
Soroush Vahidi, Ioannis Koutis
The Minimum Weighted Feedback Arc Set (MWFAS) problem is closely related to the task of deriving a global ranking from pairwise comparisons. Recent work by He et al. (ICML 2022) ad…

Feedforward Ordering in Neural Connectomes via Feedback Arc Minimization
Soroush Vahidi
We present a suite of scalable algorithms for minimizing feedback arcs in large-scale weighted directed graphs, with the goal of revealing biologically meaningful feedforward struc…
