Decision tree classification algorithm
A decision tree is based on the recursive partitioning approach (divide and conquer), which generates a set of rules that can be used to predict a label.

The decision tree ends in leaf nodes that contain the decisions. The process stops when partitioning no longer improves the outcome.
