What is this?

As part of the Machine Learning class in (CIS 678) at GVSU, Camila and Roland designed this decision tree tool that analyzes and processes a data-set, where each entry has a different combination of attributes and an expected outcome. This program then finds the «best» attributes, that allow deciding which outcome will occur with the least amount of questions, for previously seen or new data. Finally it creates a decision tree of the selected attributes.
