Adaptive Annealed Importance Sampling with Constant Rate Progress

1 code implementation27 Jun 2023 Shirin Goshtasbpour, Victor Cohen, Fernando Perez-Cruz

This algorithm relies on a sequence of interpolating distributions bridging the target to an initial tractable distribution such as the well-known geometric mean path of unnormalized distributions which is assumed to be suboptimal in general.
