我们现在描述我们的单步Q-learning、一步 Sarsa、n步Q-learning 和A2C的变体。 Asynchronous one-step Q-learning 我们称为异步单步 Q-learning 的 Q-learning 变体的伪代码如算法 1 所示。每个线程与它自己的环境副本交互,并在每一步计算 Q-learning 的梯度损失。我们使用共享且缓慢变化的目标网络来计算 Q 学习...
In value-based model-free reinforcement learning methods the action value function is represented using a function approximation, such as a neural network…. In contrast to value-based methods, policy-based model-free methods directly parameterize the policy π(a|s;θ) and update the parameters θ...

It is well known that reinforcement learning-based methods require a large number of experience samples for the modeling process to optimize the policy for a given task. Besides, the built reinforcement learning model on the experience of a single intersection may turn to be powerless when it com...
In recent years, many studies have used Deep Reinforcement Learning (DRL) methods to address the AMP problem and have achieved good results. From the perspective of sampling, this paper designs a sampling method with double-screening, combines it with the Deep Deterministic Policy Gradient (DDPG)...
