Researchers have developed a novel end-to-end algorithm for model-based reinforcement learning in partially observable environments. This algorithm addresses the challenge of inferring hidden states, learning latent dynamics, and planning under uncertainty by integrating sequential Monte Carlo methods for state filtering, online updates for dynamics models, and an approximate online planning approach using a Q-value function. The theoretical analysis provides a regret bound that decomposes error into components related to model estimation, particle filtering, Monte Carlo rollouts, and the QMDP approximation, offering insights into how statistical sample size, particle budget, rollout budget, and planning depth influence performance. The framework has been demonstrated in a model predictive control-based deep reinforcement learning setting, showing practical applicability across various environments. AI
