New RL operator tackles approximate evaluation for optimal policy improvement

Researchers have developed a novel operator for optimal policy improvement in reinforcement learning (RL) that addresses the challenge of approximate evaluation. This new operator formulates greedification under uncertainty as a probabilistic decision-making problem. Empirical results show that this operator and its gradient-based approximations enhance performance across various RL algorithms and experimental setups, including discrete and continuous actions, and both model-based and model-free approaches.
