This document discusses issues in decision tree algorithms. It introduces decision trees, outlines the procedure for decision tree learning, and provides an example. It then discusses overfitting as an issue in decision tree learning and presents the basic decision tree algorithm. The document concludes by assigning homework on decision tree representation, appropriate problems, and issues in decision tree learning.
