Terminal Node

Detailed explanation-1: -Decision Node: When a sub-node splits into further sub-nodes, then it is called the decision node. Leaf / Terminal Node: Nodes do not split is called Leaf or Terminal node. Pruning: When we remove sub-nodes of a decision node, this process is called pruning. You can say the opposite process of splitting.
Detailed explanation-2: -In these decision trees, nodes represent data rather than decisions. This type of tree is also known as a classification tree. Each branch contains a set of attributes, or classification rules, that are associated with a particular class label, which is found at the end of the branch.
Detailed explanation-3: -The process of splitting a single node into many nodes is known as splitting. A leaf node, also known as a terminal node, is a node that does not break into other nodes. A branch, sometimes known as a sub-tree, is a section of a decision tree.
Detailed explanation-4: -A decision tree (also referred to as a classification tree or a reduction tree) is a predictive model which is a mapping from observations about an item to conclusions about its target value.
Detailed explanation-5: -Splitting: Splitting is the process of dividing the decision node/root node into sub-nodes according to the given conditions. Branch/Sub Tree: A tree formed by splitting the tree. Pruning: Pruning is the process of removing the unwanted branches from the tree.
