PyRecs 0.11

Recommender systems for Python

A Python Recommender Systems library

Installation

I have only tested on Python 3.5.1

pip3 install pyrecs

Usage

Given a NUM_USERS x NUM_ITEMS matrix of ratings, predict the rating by user 0 of item 2 and by user 2 of item 0:

>>> cf = pyrecs.collab.CollaborativeFiltering()
>>> cf.fit([[10,     3.4, np.nan, None],
...         [10,     0,   10,     5],
...         [np.nan, 1.4, 10,     3],
...         [np.nan, 8,   2,      5]])
>>> cf.predict([(0, 2), (2, 0)])
array([ 10.68567893,   8.31302514])
