Score-Repellent Monte Carlo offers efficient non-Markovian sampling with constant memory

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have introduced Score-Repellent Monte Carlo (SRMC), a novel framework designed to enhance the efficiency of non-Markovian sampling in general state spaces. SRMC summarizes trajectory history using a running average of score evaluations, enabling it to discourage redundant revisits and reduce Monte Carlo variance. This approach maintains constant memory usage and offers improved estimator variance and mode coverage compared to existing methods, as demonstrated in experiments on continuous targets and discrete energy-based models.
