This repository contains a solution to a Kaggle competition of Distributed Information Systems course of EPFL. The competition is about the creation of a Recommendation Engine for the MovieLens dataset, which is automatically evaluated in the competition using RMSE.

We describe our approach in our report (report/Report.pdf), as well us our final submission notebook (src/kaggle.ipynb). Briefly, we utilize an optimized Matrix Factorization approach to generate user rating predictions.
