MIMI: Mutual Information-Maximizing Interface

MIMI is an algorithm for training an interface to map user command signals to system actions through unsupervised human-in-the-loop reinforcement learning.

Usage

1. Clone mimi into your home directory ~
2. Download data.zip and decompress it into mimi/
3. Setup an Anaconda virtual environment with conda create -n mimienv python=3.6
4. Install dependencies with pip install -r requirements.txt and pip install pyglet==1.5.11
5. Replace your_install_dir/gym/envs/box2d/lunar_lander.py with deps/box2d/lunar_lander.py
6. Install the mimi package with python setup.py install
7. Jupyter notebooks in mimi/notebooks provide an entry-point to the code base, where you can play around with the environments and reproduce the figures from the paper.
