Clipped q-learning

WebQ-learning, we propose a simple heuristic that utilizes real return signals as a lower bound estimation to rule out the potential non-optimal fixed points. Benefiting from its simplicity, this method is easy to be combined with other existing techniques such as clipped double Q-learning. In the experiments WebDec 6, 2024 · Due to the introduction of the “Clipped Double-Q Learning” like TD3, plus the inherent smoothing characteristics of the stochastic strategy, the training process of SAC fluctuates within a very small range, and the exploration of the environment is sufficient.

WebWe show that Q-learning’s performance can be poor in stochastic MDPs because of large overestimations of the action val-ues. We discuss why this occurs and propose an algorithm called Double Q-learning to avoid this overestimation.
