New Gibbs distribution enhances Monte Carlo integration accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel Gibbs distribution designed to improve Monte Carlo integration methods. This distribution's support concentrates around MMD minimizers as a temperature parameter decreases, offering tighter concentration inequalities and smaller confidence intervals compared to standard Monte Carlo quadrature, particularly in infinite-dimensional reproducing kernel Hilbert spaces. While the theoretical error bounds match i.i.d. Monte Carlo, the improved concentration provides a practical advantage. Numerical experiments using a simple MCMC chain demonstrate that sampling from this Gibbs distribution yields approximate samples that enhance confidence intervals for target integrals, aligning with the theoretical findings.

    Monte Carlo with kernel-based Gibbs measures: Guarantees for probabilistic herding

    arXiv:2402.11736v3 Announce Type: replace-cross Abstract: Kernel herding belongs to a family of deterministic quadratures that seek to minimize the maximum mean discrepancy (MMD), that is, the worst-case integration error over a reproducing kernel Hilbert space (RKHS). These MMD …
