WebA common failure mode for DDPG is that the learned Q-function begins to dramatically overestimate Q-values, which then leads to the policy breaking, because it exploits the … 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
WebJan 27, 2024 · KerasRL. KerasRL is a Deep Reinforcement Learning Python library. It implements some state-of-the-art RL algorithms, and seamlessly integrates with Deep Learning library Keras. Moreover, KerasRL works with OpenAI Gym out of the box. This means you can evaluate and play around with different algorithms quite easily. 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. The update of Q-learning is Qt+1(st,at) = Qt(st,at)+αt(st,at) rt +γmax a Qt(st+1,a)−Qt(st,at) . (1)
