Among all the online purchases that occur every day, a few are frauds. Finding these is a hard and cumbersome task and today we use a semi-automatic system for this. The next phase is to improve fraud detection through machine learning. We present the process of converting raw data into features, training models on these features and getting a prediction system up and running.
