Resources

• OpenAI Baselines for useful Atari wrappers and replay buffer
• bearpaw's pytorch-classification repo for utilities, logging, training framework
• ikostrikov's PPO implementation for other utilities and PPO guidance
• pytorch-rl for DQN help
• PyTorch DQN tutorial for PyTorch tricks
• Original DQN paper since both papers use the original hyperparameters, for the most part

TODOs

• Implement PPO and MuJoCo env handling
• Revisit logging; make sure everything is there to reproduce results in papers
• Implement plotting (matplotlib is in Logger object; maybe try out visdom)
• More tests (figure out different combinations of arguments to ensure everything's interacting well)
• Begin experiments (start with Mujoco; it's cheaper)

Atari Games to Test

• Alien: Adaptive helps a lot, learned shows no improvement
• Enduro: Both methods improve
• Seaquest: Adaptive helps, learned performs worse than baseline
• Space Invaders: Adaptive helps, but learned helps more
• WizardOfWor: Adaptive worse than baseline, but learned helps a lot

MuJoCo enviroments to test

• Hopper
• Walker2d
• HalfCheetah
• Sparse versions of these? (from rllab)
