New sampling frameworks improve Ising models and Bayesian regression

By PulseAugur Editorial · [1 sources] ·

Researchers have developed new frameworks for sampling problems in high-dimensional statistical settings, specifically focusing on Ising models and Bayesian sparse linear regression. These frameworks allow for improved samplers in fixed-magnetization Ising models, even at low temperatures under strong external fields. Additionally, the work reduces the measurement requirements for sampling from Gaussian spike-and-slab posteriors in Bayesian sparse linear regression, improving upon previous results. AI

    High-Magnetization Sampling at Low Temperatures: Ising Models and Bayesian Sparse Linear Regression

    arXiv:2609.08873v1 Announce Type: cross Abstract: Sparsity is a powerful structural resource in optimization and statistics. We develop frameworks for leveraging sparsity in sampling problems over the Hamming slice $\mathcal{X}_k^d:=\{\mathbf{x}\in\{\pm 1\}^d:|\{i:\mathbf{x}_i=1\…
