arXiv:2510.11711v2 Announce Type: replace Abstract: This paper proposes a synergy of amortised and particle-based methods for sampling from distributions defined by unnormalised density functions. We state a connection between sequential Monte Carlo (SMC) and neural sequential samplers trained by maximum-entropy reinforcement learning (MaxEnt RL), wherein learnt sampling policies and value functions define proposal kernels and twist functions. Exploiting this connection, we introduce an off-policy RL training procedure for the sampler that uses samples from SMC -- using the learnt sampler as a
This research builds on recent advances in AI, specifically reinforcement learning and neural samplers, to address a fundamental challenge in complex probabilistic modeling.
Improved sampling methods can unlock more efficient and accurate AI models, impacting domains from scientific simulation to generative AI and autonomous systems.
The ability to sample from complex, unnormalised distributions more efficiently could lead to more robust and capable AI applications, reducing computational bottlenecks for certain tasks.
