New research unifies KL divergence gradient flows for statistical inference

A new research paper introduces a unified framework for analyzing statistical inference algorithms, focusing on the inclusive Kullback-Leibler (KL) divergence. The work establishes gradient-flow and probability density function (PDF) frameworks, demonstrating how maximum mean discrepancy (MMD) minimization can be viewed as inclusive KL inference. The paper also develops Fisher-Rao and Wasserstein-Fisher-Rao gradient flows for inclusive KL divergence and proposes a local-estimator Wasserstein gradient flow that improves algorithmic performance over MMD-based methods.

    Inclusive KL Gradient Flows: Otto-Wasserstein, Fisher-Rao-Gaussian, and Local-Estimator Dynamics

    arXiv:2411.00214v2 Announce Type: replace Abstract: Otto's Wasserstein gradient flow of the inclusive (forward) Kullback--Leibler (KL) divergence offers a principled framework for analyzing statistical inference algorithms, yet algorithms targeting the exclusive (reverse) KL dive…
