Description
A subproject of Machine Intelligence Core framework.
The repository contains solutions and applications related to (deep) reinforcement learning. In particular, it contains several classical problems (N-armed bandits, several variations of Gridworld), POMDP environments (Gridworld, Maze of Digits, MNIST digit) and algorithms (from simple Value Iteartion and Q-learning to DQN with Experience Replay).
Applications
- mnist_patch_autoencoder_reconstruction – application realizing MNIST patch autoencoder-based reconstruction
- mnist_patch_autoencoder_softmax – application realizing MNIST patch autoencoder-based softmax classifier, using the imported, previously trained auto-encoder
- mlnn_sample_training_test – (test) application for testing of training of a multi-layer neural network
- mlnn_batch_training_test – (test) application for testing batch training of a multi-layer neural network
- mnist_convnet – (test) application using Convolutional Neural Network for recognition of MNIST digits
- mnist_simple_mlnn_app – (test) application using a simple multi-Layer neural net for recognition of MNIST digits
- mnist_batch_visualization_test – the MNIST batch visualization test application
- mnist_mlnn_features_visualization_test – program for visualization of features of mlnn layer trained on MNIST digits
Unit tests
- loss/lossTestsRunner – loss functions unit tests
- optimization/artificialLandscapesTestsRunner – artificial landscapes used for optimization testing unit tests
- optimization/optimizationFunctionsTestsRunner – unit tests of different optimization functions/methods
- mlnn/mlnnTestsRunner – unit tests for multi-layer neural network
- mlnn/cost_function/softmaxTestsRunner – unit tests of the softmax layer
- mlnn/fully_connected/linearTestsRunner – unit tests for linear (fully-connected) layer
External dependencies
Additionally it depends on the following external libraries:
- Boost - library of free (open source) peer-reviewed portable C++ source libraries.
- Eigen - a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
- OpenGL/GLUT - a cross-language, cross-platform application programming interface for rendering 2D and 3D vector graphics.
- OpenBlas (optional) - An optimized library implementing BLAS routines. If present - used for fastening operation on matrices.
- Doxygen (optional) - Tool for generation of documentation.
- GTest (optional) - Framework for unit testing.
Installation of the dependencies/required tools
On Linux (Ubuntu 14.04):
sudo apt-get install git cmake doxygen libboost1.54-all-dev libeigen3-dev freeglut3-dev libxmu-dev libxi-dev
To install GTest on Ubuntu:
sudo apt-get install libgtest-dev
On Mac (OS X 10.14): (last tested on: Feb/01/2019)
brew install git cmake doxygen boost eigen glfw3
To install GTest on Mac OS X:
brew install --HEAD https://gist.githubusercontent.com/Kronuz/96ac10fbd8472eb1e7566d740c4034f8/raw/gtest.rb
MIC dependencies
Installation of all MIC dependencies (optional)
This step is required only when not downloaded/installed the listed MIC dependencies earlier.
In directory scripts one can find script that will download and install all required MIC modules.
git clone git@github.com:IBM/mi-neural-nets.git
cd mi-neural-nets
./scripts/install_mic_deps.sh ../mic
Then one can install the module by calling the following.
./scripts/build_mic_module.sh ../mic
Please note that it will create a directory 'deps' and download all sources into that directory. After compilation all dependencies will be installed in the directory '../mic'.
Installation of MI-Neural-Nets
The following assumes that all MIC dependencies are installed in the directory '../mic'.
git clone git@github.com:IBM/mi-neural-nets.git
cd mi-neural-nets
./scripts/build_mic_module.sh ../mic
Make commands
- make install - install applications to ../mic/bin, headers to ../mic/include, libraries to ../mic/lib, cmake files to ../mic/share
- make configs - install config files to ../mic/bin
- make datasets - install config files to ../mic/datasets
Documentation
In order to generate a "living" documentation of the code please run Doxygen:
cd mi-neural-nets
doxygen mi-neural-nets.doxyfile
firefox html/index.html
The current documentation (generated straight from the code and automatically uploaded to github pages by Travis) is available at:
