• Branch: Used to connect different nodes.

Here are some additional terms commonly used in decision trees:

• Internal nodes: All nodes between the root node and the leaf nodes (decision nodes and chance nodes) are called internal nodes. It can have any number of internal nodes.

• Pruning: Pruning is a method used to remove nodes containing irrelevant data when a decision tree becomes complex.

• Splitting: When a node is split into two or more subnodes, it is called splitting or bifurcation. These subnodes can be internal nodes or end nodes.
