Web# Each row of the replay buffer only stores a single observation step. But since the DQN Agent needs both the current and next observation to compute the loss, the dataset pipeline will sample two adjacent rows for each item in the batch (`num_steps=2`). # # This dataset is also optimized by running parallel calls and prefetching data. # In[29]: WebReplay Dataset: Collection of all samples generated by online policy during training; ... Algorithms of the DQN family that search unconstrained for the optimal policy were found to require datasets with high SACo to find a good policy. Finally, algorithms with constraints towards the behavioural policy were found to perform well if datasets ...

WebFirstly, because of the poor performance of traditional DQN, we propose an improved DQN-D method, whose performance is improved by 62% compared with DQN. Second, for RNN-based DRL, we propose a method based on improved experience replay pool (DRQN) to make up for the shortcomings of existing work and achieve excellent performance.
