• ./recysys.py trains the recommender system
• ./results directory used for storing model reports and results
• ./docs: research notes etc

1. Clone this repo and cd to root
2. Download, unzip and store the ratings data:
   1. $ mkdir data
   2. $ wget 'http://files.grouplens.org/datasets/movielens/ml-1m.zip'

   4. $ mv ./ml-1m/ratings.dat ./data/
   5. $ rm -rf ml-1m
   6. $ rm ml-1m.zip
