This update introduces one of the main concepts of Wanda++ (arXiv), Regional Gradient Score (RGS).
Algorithm : RGS
RGS uses block-level gradients instead of magnitude (Wanda):
G_ij: Regional gradient||X_j||_2: Activation norm (same in Wanda)|W_ij|: Weight magnitude (same in Wanda)α: Regional gradient weight (default: 100 from paper)Algorithm : Wanda++
