Robust inference using density-powered Stein operators

arXiv:2511.03963v3 Announce Type: replace Abstract: We introduce a density-power weighted variant of the Stein operator, called the $gamma$-Stein operator, for robust inference with unnormalized probability models. The operator is motivated by the first variation of the $gamma$-divergence under infinitesimal escort t
