Kaggle provides an unbalanced dataset containing numerical variables of 284,807 credit card transactions made within a span of two days in September 2013 to use for machine learning related projects. In this project, 492 transactions are fraudulent, making the positive class approxiately 0.172% of all transactions. Datasheet can be found and downloaded here

This project was led by Siddhardhan, a Machine Learning Engineer, during a Machine Learning Workshop.
The dataset has been collected and analysed during a research collaboration of Worldline and the Machine Learning Group http://mlg.ulb.ac.be of ULB (Université Libre de Bruxelles) on big data mining and fraud detection. More details on current and past projects on related topics are available on https://www.researchgate.net/project/Fraud-detection-5 and the page of the DefeatFraud project.
