Research paper analyzes $\alpha$-divergence generalized posteriors

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the asymptotic behavior of generalized variational inference solutions when regularized by an $\alpha$-divergence. The study reveals that under certain conditions, the minimizer of this problem can be explicitly determined and exhibits a rescaling property. The paper details how the limit of this rescaled minimizer depends on the value of $\alpha$, leading to different distributions such as Student-t or Pearson type-II, and impacting the posterior width relative to the sampling error. The Kullback–Leibler divergence, corresponding to $\alpha=1$, is identified as the unique case where the posterior width matches the sampling scale and the limit is Gaussian. AI

    On the asymptotic behaviour of $\alpha$-divergence generalized posteriors

    arXiv:2610.35330v1 Announce Type: cross Abstract: We study the asymptotic behaviour of the solutions to the unconstrained generalized variational inference problem regularized by an $\alpha$-divergence. Under mild conditions, the minimizer is explicit up to a scalar normalizing c…
