This is a repository for labs of EE359: Data Mining Techniques in Shanghai Jiao Tong University. Currently, two labs are completed, which are

• Lab 1: clustering
• Lab 2: community detection
• Lab 3: link prediction

Kaggle competition is available at: https://www.kaggle.com/c/datamining-2021.

We mainly implement K-Means Algorithm in the clustering lab.
