Goal(s): The goal of this workshop is to teach participants how to create a decision tree model using the Knime Analytics Platform

Outcomes: Participants will be able to use the Knime Analytics Platform to build a basic decision tree model.

Description: This hands-on introduction to the Knime Analytics Platform will guide participants through the process of constructing a decision tree to model 2016 votes for Donald Trump in Texas using various demographic attributes. “A decision tree is a decision support tool that uses a tree-like model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm that only contains conditional control statements.” (https://en.wikipedia.org/wiki/Decision_tree)
