* Add the Advantage Weighted Actor Critic (AWAC) algorithm from (Nair et al., 2020)[1]. * Include two examples. The first is used as a offline RL algorithm on the D4RL dataset. The second example demonstrates how to perform pre-training with online finetuning on D4RL tasks. Notes: - This implementation is implemented with reference to https://github.com/ikostrikov/jaxrl/blob/main/jaxrl/agents/awac/awac_learner.py and is a port from the Flax implementation to use Haiku + Acme. - Another source of reference would be https://www.github.com/rail-berkeley/rlkit/tree/master/rlkit which is the "official" implementation, this version however includes a lot of flags to switch between different algorithms and is difficult to understand what is happening. - AWAC is very similar to the CRR algorithm, with differences in how to normalize the advantages and the base RL off-policy algorithm.

@dennisushi AWAC will be available when this is merged. There are some remaining lint errors but should be easy to fix. Feel free to take a look at the examples and let me know of anything that's unclear. |
