New algorithm enhances stability for mean-field variational inference

Researchers have developed a finite-batch particle algorithm for mean-field variational inference, extending its stability beyond strongly convex potentials. The algorithm is analyzed as a discrete approximation of projected Wasserstein dynamics, with a focus on quantifying the departure from contractivity using a curvature defect. This work provides non-asymptotic bounds on the Wasserstein stability, separating various error sources and establishing conditions under which particle iterates remain close to a minimizer. AI

IMPACT Introduces a more robust method for mean-field variational inference, potentially improving the performance of related AI models.
