New CAT method improves multimodal sampling by addressing mode collapse

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called componentwise annealed transport (CAT) to address mode collapse in multimodal sampling. This technique learns separate transport maps along componentwise annealing paths, starting from a mode-informed mixture reference. Experiments on synthetic distributions and Bayesian inference problems show that CAT improves transport learning and sampling efficiency, even with inexact learned flows and adaptive annealing schedules.

    Transport along Local Annealing Paths: Wasserstein Geometry and Multimodal Sampling

    arXiv:2611.05605v1 Announce Type: new Abstract: Variational approaches to learning transport maps for multimodal sampling can suffer from mode collapse. One way to mitigate this problem is to learn transport along a prescribed path of intermediate distributions defined by geometr…
