The topmost decision node in a tree which corresponds to the best predictor called root node. Attribute Selection Measures Attribute selection measure is a heuristic for selecting the splitting criterion that partition data into the best possible manner.
Creating a binary decision tree is actually a process of dividing up the input space. Mirrors human decision making more closely than other approaches. If the sample is completely homogeneous the entropy is zero and if the sample is an equally divided it has entropy of one.

Conclusion Decision Tree Algorithm A decision tree is a flowchart-like tree structure where an internal node represents feature or attributethe branch represents a decision rule, and each leaf node represents the outcome.
Descriptions This section provides a brief introduction to the Classification and Regression Tree algorithm and the Banknote dataset used in this tutorial.
This maximizes the information gain and creates useless partitioning.
