  • Resonances in reflective Hamiltonian Monte Carlo

    Resonances in reflective Hamiltonian Monte Carlo arXiv:2504.12374v1 Announce Type: new Abstract: In high dimensions, reflective Hamiltonian Monte Carlo with inexact reflections exhibits slow mixing when the particle ensemble is initialised from a Dirac delta distribution and the uniform distribution is targeted. By quantifying the instantaneous non-uniformity of the distribution with the Sinkhorn divergence, we elucidate…

  • Robust and Scalable Variational Bayes

    Robust and Scalable Variational Bayes arXiv:2504.12528v1 Announce Type: new Abstract: We propose a robust and scalable framework for variational Bayes (VB) that effectively handles outliers and contamination of arbitrary nature in large datasets. Our approach divides the dataset into disjoint subsets, computes the posterior for each subset, and applies VB approximation independently to these posteriors.…
