Overview

The Customer Churn lab is derived from the data-science-blueprints repo, where customer churn is modeled from federating data and performing exploratory query-based analytics to feature engineering, model training, and model operationalization. The data engineering portions of the blueprint are accelerated with the RAPIDS Accelerator for Apache Spark and the machine learning portions are accelerated with the RAPIDS Python libraries.This lab shows a realistic ETL workflow based on synthetic normalized data. It consists of two pieces:

• An augmentation script, which synthesizes normalized (long-form) data from a wide-form input file, optionally augmenting it by duplicating records.

• An ETL script, which performs joins and aggregations in order to generate wide-form data from the synthetic long-form data.
