Machine Learning 101 - Decision Trees

Overview

This hands on tutorial demonstrates the basics of developing a machine learning routine using Talend and Spark. Specifically, decision tree learning will be leveraged for classification of real-life bank marketing data. Upon completion, you will have a working knowledge of how machine learning is integrated into a Talend workflow and some re-usable code snippets.
