Chapter 5. Classifying Data with Tableau
In this chapter, we will look at ways to perform classification using R and visualizing the results in Tableau. Classification is one of the most important tasks in analytics today. By the end of this chapter, you'll build a decision tree, while retaining a focus on a business-oriented understanding of the business question using classification algorithms.
When we are modeling data, it is crucial to keep the original business objectives in mind. These business objectives will direct the subsequent work in the data understanding, preparation and modeling steps, and the final evaluation and selection (after revisiting earlier steps if necessary) of a classification model or models.
