Flow annealed importance sampling bootstrap
WebAug 3, 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 … 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 bring the samples from the flow model closer to the target, reducing variance in the objective. In our experiments, we apply our method, F low A IS B ootstrap (FAB), to a …
