In this session, PayPal will present the techniques used to retain merchants using some of the Machine Learning models using SparkML platform. Retaining merchants directly equates to Dollar value. So, it was very critical for us to identify the right model that trains on our data and predicts merchant behavior giving us insights that help us prevent merchant churn. We will also deep dive on how we captured the right signals filtering the noise that could skew the predictions and some of the challenges we faced in scaling this solution. Lastly, we will see how SparkML orchestrated various events in the pipeline we built thereby enabling us to perform feature engineering, train it, validate and cross-validate it at scale across the different data samples we had.
