----- DQN 3.0 ----- This project contains the source code of DQN 3.0, a Lua-based deep reinforcement learning architecture, necessary to reproduce the experiments described in the paper "Human-level control through deep reinforcement learning", Nature 518, 529–533 (26 February 2015) doi:10.1038/nature14236. To replicate the experiment results, a number of dependencies need to be installed, namely: * LuaJIT and Torch 7.0 * nngraph * Xitari (fork of the Arcade Learning Environment (Bellemare et al., 2013)) * AleWrap (a lua interface to Xitari) An install script for these dependencies is provided. Two run scripts are provided: run_cpu and run_gpu. As the names imply, the former trains the DQN network using regular CPUs, while the latter uses GPUs (CUDA), which typically results in a significant speed-up. ----- Installation instructions ----- The installation requires Linux with apt-get. Note: In order to run the GPU version of DQN, you should additionally have the NVIDIA CUDA (version 5.5 or later) toolkit installed prior to the Torch installation below. This can be downloaded from https://developer.nvidia.com/cuda-toolkit and installation instructions can be found in http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux To train DQN on Atari games, the following components must be installed: * LuaJIT and Torch 7.0 * nngraph * Xitari * AleWrap To install all of the above in a subdirectory called 'torch', it should be enough to run ./install_dependencies.sh from the base directory of the package. Note: The above install script will install the following packages via apt-get: build-essential, gcc, g++, cmake, curl, libreadline-dev, git-core, libjpeg-dev, libpng-dev, ncurses-dev, imagemagick, unzip ----- Training DQN on Atari games ----- Prior to running DQN on a game, you should copy its ROM in the 'roms' subdirectory. It should then be sufficient to run the script ./run_cpu Or, if GPU support is enabled, ./run_gpu Note: On a system with more than one GPU, DQN training can be launched on a specified GPU by setting the environment variable GPU_ID, e.g. by GPU_ID=2 ./run_gpu If GPU_ID is not specified, the first available GPU (ID 0) will be used by default. ----- Options ------ Options to DQN are set within run_cpu (respectively, run_gpu). You may, for example, want to change the frequency at which information is output to stdout by setting 'prog_freq' to a different value.
