Researchers have developed a new model-based framework for continuous-time policy evaluation in reinforcement learning. This approach accounts for both Brownian and Lévy noise, which are crucial for modeling rare and extreme events. The method involves solving a complex partial integro-differential equation and includes a novel iterative tail correction mechanism to accurately recover unknown coefficients in the stochastic dynamics, particularly those driven by heavy-tailed Lévy processes. The effectiveness of this robust numerical approach has been demonstrated through numerical experiments, including an analysis of real-world Bitcoin price data. AI
