Double Q Learning

Double Q-learning is a reinforcement learning technique designed to mitigate the overestimation bias inherent in standard Q-learning, improving the accuracy of value estimations and ultimately leading to better policy learning. Current research focuses on enhancing its efficiency and applicability, exploring variations like simultaneous updates, incorporating expectile losses for pessimism, and integrating it within other architectures such as actor-critic methods and ensembles. These advancements are significant because they improve the sample efficiency and robustness of reinforcement learning algorithms, leading to better performance in various applications, from robotics and game playing to more complex domains like financial modeling and cybersecurity.
