Web4. What is a Decision Tree Algorithm? A Decision Tree is a tree-like graph with nodes representing the place where we pick an attribute and ask a question; edges represent the answers to the question, and the leaves represent the actual output or class label. They are used in non-linear decision making with a simple linear decision surface.
