Distributional DQN

Implementation of 'A Distributional Perspective on Reinforcement Learning' and 'Distributional Reinforcement Learning with Quantile Regression' based on OpenAi DQN baseline.

C51:

c51

Quantile Regression: (see branch quantile)

quantile regression

Installation

Install the OpenAi fork https://github.com/Silvicek/baselines (parent changes a lot, compatibility isn't guaranteed) Then install requirements

pip3 install -r requirements.txt

Usage:

For simple benchmarking:

python3 train_[{cartpole, pong}].py
python3 enjoy_[{cartpole, pong}].py

For full Atari options see help

python3 train_atari.py --help

after learning, you can visualize the distributions by running

python3 enjoy_atari.py --visual ...

This implementation has been successfully tested on: Pong, Qbert, Seaquest

Some baseline features not supported (prioritized replay, double q-learning, dueling)
