This is an implementation of the method proposed in
RIDE: Rewarding Impact-Driven Exploration for Procedurally-Generated Environments
by Roberta Raileanu and Tim Rocktäschel, published at ICLR 2020.
We propose a novel type of intrinsic reward which encourges the agent to take actions that result in significant changes to its representation of the environment state.
The code includes all the baselines and ablations used in the paper.
The code was also used to run the baselines in Learning with AMIGO: Adversarially Motivated Intrinsic Goals. See the associated repo for instructions on how to reproduce the results from that paper.

To train RIDE on the other MiniGrid environments used in our paper, replace the --env argument above with each of the following:
MiniGrid-MultiRoom-N7-S4-v0
MiniGrid-MultiRoomNoisyTV-N7-S4-v0
MiniGrid-MultiRoom-N7-S8-v0
MiniGrid-MultiRoom-N10-S4-v0
MiniGrid-MultiRoom-N10-S10-v0
MiniGrid-MultiRoom-N12-S10-v0
MiniGrid-ObstructedMaze-2Dlh-v0
MiniGrid-KeyCorridorS3R3-v0
Make sure to use the best hyperparameters for each environment, as listed in the paper.
To run different seeds for a model, change the --run_id argument.
Our vanilla RL algorithm is based on Torchbeast, which is an open source implementation of IMPALA.
