New Polynomial Stein Discrepancy method improves Bayesian inference sample quality assessment

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
