Lucid Dreaming for Experience Replay: Refreshing Past States with the Current Policy

1 code implementation29 Sep 2020 Yunshu Du, Garrett Warnell, Assefaw Gebremedhin, Peter Stone, Matthew E. Taylor

In this work, we introduce Lucid Dreaming for Experience Replay (LiDER), a conceptually new framework that allows replay experiences to be refreshed by leveraging the agent's current policy.

Pre-training with Non-expert Human Demonstration for Deep Reinforcement Learning

1 code implementation21 Dec 2018 Gabriel V. de la Cruz, Yunshu Du, Matthew E. Taylor

Deep reinforcement learning (deep RL) has achieved superior performance in complex sequential tasks by using deep neural networks as function approximators to learn directly from raw input images.
