New Polynomial Stein Discrepancy method improves Bayesian inference sample quality assessment

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced the Polynomial Stein Discrepancy (PSD), a new method to evaluate the quality of samples generated by Bayesian inference algorithms. This approach aims to overcome the scalability and dimensionality limitations of existing methods like the kernel Stein Discrepancy (KSD). The PSD offers a more computationally efficient way to assess moment convergence and can aid in hyper-parameter tuning for Bayesian sampling algorithms. AI

IMPACT Introduces a more efficient method for assessing sample quality in Bayesian inference, potentially improving hyper-parameter tuning for complex models.

    The Polynomial Stein Discrepancy for Assessing Moment Convergence

    arXiv:2412.05135v2 Announce Type: replace Abstract: We propose a novel method for measuring the discrepancy between a set of samples and a desired posterior distribution for Bayesian inference. Classical methods for assessing sample quality like the effective sample size are not …
