arXiv:2606.16073v1 Announce Type: new Abstract: Sampling from complex, unnormalized probability densities is a fundamental challenge in Bayesian inference and probabilistic modeling. While Markov chain Monte Carlo (MCMC) methods provide asymptotic guarantees, they often suffer from slow mixing and high computational costs due to fixed or manually tuned trajectory lengths. In this work, we propose a novel framework that treats trajectory termination as a learnable component of the sampling dynamics. By framing MCMC within the theory of non-acyclic generative flow networks (GFlowNets), we train
The increasing complexity of probabilistic models and the demand for more efficient Bayesian inference are driving innovation in sampling methods.
Improved sampling techniques can significantly accelerate progress in AI development, particularly in areas relying on complex probabilistic modeling and uncertainty quantification.
This research introduces a novel, adaptive approach to MCMC sampling that promises to enhance efficiency and reduce computational costs by dynamically optimizing trajectory lengths.
