Groups Don't Move as One: A Bregman Clustering View of Linearized Group Influence

Hyunho Choi, Jaeseung Heo, Youngbin Choi +2

Influence functions provide an efficient alternative to retraining for assessing the effects of removing or reweighting training data. For groups, however, the standard first-order…

Mitigating Oversmoothing Through Reverse Process of GNNs for Heterophilic Graphs

MoonJeong Park, Jaeseung Heo, Dongwoo Kim

Graph Neural Network (GNN) resembles the diffusion process, leading to the over-smoothing of learned representations when stacking many layers. Hence, the reverse process of messag…
