Datasets

1. Cardiovascular disease dataset (cardio): cardio_train.csv (sourced from here)
2. Bank customer churn prediction dataset (churn): Bank Customer Churn Prediction.csv (sourced from here)
3. Default of credit card clients dataset (default): default of credit card clients.csv (sourced from here)

Codes

1. To compute row leverage scores of a matrix: leverage_scores.py
2. To perform leverage score, l2s, or uniform sampling: row_sampling.py

The code for l2s sampling has been sourced from here.
