A type of supervised machine learning whereby the correct answers are given along with the model inputs in the training phase, a decision tree comprises decision nodes with two outcomes. See AI types, fat tree topology and machine learning.
Decision Tree Structure
A Loan Example
Starting with the root node, there is no limit to the number of decision nodes, also called "internal nodes." The leaf nodes, also called "terminal nodes," are the outcomes, which may be results or actions that must take place. See next diagram.
Highly simplified, nevertheless this example shows how decisions are made using a decision tree.
