Flow annealed importance sampling bootstrap
WebTo address these challenges, we propose using the α-divergence with α = 2 as the training objective, which is mass covering, and employ annealed importance sampling (AIS) to … WebFeb 1, 2024 · To avoid these problems, we augment flows with annealed importance sampling (AIS) and minimize the mass-covering $\alpha$-divergence with $\alpha=2$, which minimizes importance weight variance. Our method, Flow AIS Bootstrap (FAB), uses AIS to generate samples in regions where the flow is a poor approximation of the …
