PCHID_code

Code for Policy Continuation with Hindsight Inverse Dynamics (PCHID)

There are three environments

• Bitflip

The bitflip environment was introduced by Hindsight experience replay (HER)

Our implementation of bitflip and HER refers RL-Adventure-2 and Baselines

• GridWorld

Our experiment on the GridWorld domain is based on previous work of Value Iteration Networks (VIN) and the PyTorch implementation of VIN

• FetchReach

The FetchReach environment is one of four OpenAI Fetch envs. As for the other three environments (Push, Slide, PickAndPlace), synchoronous improvement is needed to further improve PCHID's learning efficiency.
