New algorithm tackles reinforcement learning for diffusion processes

Researchers have developed a novel model-based algorithm for reinforcement learning in controlled diffusion processes. This algorithm addresses challenges in continuous and high-dimensional domains by adaptively partitioning the state-action space. It maintains estimators for drift, volatility, and rewards within each partition, refining the discretization to balance exploration and approximation. The theoretical analysis provides regret bounds applicable to unbounded domains, extending existing results for bounded settings, and the approach has been validated through numerical experiments, including multi-asset portfolio selection.
