Decision tree machine learning.

DTs are composed of nodes, branches and leafs. Each node represents an attribute (or feature), each branch represents a rule (or decision), and each leaf represents an outcome. The depth of a Tree is defined by the number of levels, not including the root node. In this example, a DT of 2 levels.A decision tree is a support tool with a tree-like structure that models probable outcomes, cost of resources, utilities, and possible consequences. ...
