Quick questions. Prioritized experience replay is a just sampling method. It should only affect the way we sample from replay buffer. Why changing the loss function to be a weighted one? Have you tested the performance? |

Please have a look at the Line 13 of the algorithm described in PER paper. I had only checked for Breakout. Gave a slight performance improvement over DQN. Please have a look at Kaixhin/Rainbow#15 and let me know. |
