Quenched Ensemble Sampling Tackles Phase-Transition Bottlenecks in Sampling
A new arXiv preprint introduces Quenched Ensemble Sampling, a method aimed at the difficulty of drawing samples from physical energy functions near phase transitions, where the density of states shifts sharply and many existing samplers slow or stall. The work builds on nested sampling, a particle-based approach that traverses such landscapes. The abstract indicates the technique is designed to keep sampling efficient in these abrupt regime changes.
