New research defines tractability limits for sampling with inexact scores

By PulseAugur Editorial · [1 sources] ·

This research paper introduces a precise characterization of the conditions under which sampling is feasible with inexact score oracle access. The findings indicate that any error level weaker than the sub-Gaussian assumption previously established by YW26 prevents unbiased sampling. This work extends the conclusions of CCSW26, demonstrating their applicability across various error assumptions and algorithmic approaches. AI

IMPACT Establishes theoretical limits for sampling algorithms, impacting the design and analysis of future statistical and machine learning methods.

    The Tractability Landscape of Sampling with Inexact Scores

    arXiv:2607.19004v1 Announce Type: cross Abstract: We provide a simple and tight characterization of the types of inexact score oracle access that permit sampling with vanishing total variation bias, for a standard, well-behaved target family. Our main result shows that any weaker…
