Asynchronous deep reinforcement learning

An attempt to repdroduce Google Deep Mind's paper "Asynchronous Methods for Deep Reinforcement Learning."

Asynchronous Advantage Actor-Critic (A3C) method for playing "Atari Pong" is implemented with TensorFlow.

Learning result movment after 24 hour is like this.

Any advice or suggestion is strongly welcomed in issues thread.

First we need to build multi thread ready version of Arcade Learning Enviroment. I made some modification to it to run it on multi thread enviroment.

$ git clone https://github.com/miyosuda/Arcade-Learning-Environment.git
$ cd Arcade-Learning-Environment
$ cmake -DUSE_SDL=ON -DUSE_RLGLUE=OFF -DBUILD_EXAMPLES=ON .
$ make -j 4

$ pip install .

I recommend to install it on VirtualEnv environment.

To train,

$python a3c.py

To display the result with game play,

$python a3c_disp.py
