Game recommender

WARNING - This is a toy project for course. The tech or tools used here might out of date!! But it is fun to use simple KNN and SVD to build a dynamic recommender system.

A simple Steam Game recommender website. The recommendation result is dynamic, based on the game user puchased and what user click on the web page.
