Random Walk

• Implement Random Walk (run RW.py) in Python3.
• Random Walk estimates the user's preference on an item via the average of all reachable users' preference on that item.

Dataset describe: MovieLens100K; 943 Users; 1682 Items

• More details about MovieLens datasets at https://grouplens.org/datasets/movielens .
• Our code does not depend on the datasets. Just split the dataset you are interested in into the training set and test set, replace the train.txt and test.txt files, you can run Random Walk easily.
