Improving experience replay
Witryna经验回放（experience replay） 在DQN算法中，为了打破样本之间关联关系，通过经验池，采用随机抽取经历更新参数。但是，对于奖励稀疏的情况，只有N多步正确动作后才有奖励的问题，会存在能够激励Agent进行正确学习的样本很少，采用随机抽取经历得方式，效率会很低，很多样本都奖励为0的，没 ...

Figure 5 and 6 of this paper: Revisiting Fundamentals of Experience Replay (Fedus et al., 2024) In both studies, n n -step returns show to be the critical component. Adding n n -step returns to the original DQN makes the agent improve with larger replay capacity, and removing … WitrynaExperience Replay is a method of fundamental importance for several reinforcement learning algorithms, but it still presents many questions that have not yet been exhausted and problems that are still open, mainly those related to the use of experiences that can contribute more to accelerate the agent’s learning.
Witryna29 lip 2024 · The sample-based prioritised experience replay proposed in this study is aimed at how to select samples to the experience replay, which improves the training speed and increases the reward return. In the traditional deep Q-networks (DQNs), it is subjected to random pickup of samples into the experience replay. Witryna19 paź 2024 · Reverse Experience Replay. This paper describes an improvement in Deep Q-learning called Reverse Experience Replay (also RER) that solves the problem of sparse rewards and helps to deal with reward maximizing tasks by sampling transitions successively in reverse order.
