WebDecision tree learning employs a divide and conquer strategy by conducting a greedy search to identify the optimal split points within a tree. This process of splitting is then repeated in a top-down, recursive manner until all, or the majority of records have been classified under specific class labels.

When a sub-node splits into further sub-nodes, it is called a Decision Node. Nodes that do not split is called a Terminal Node or a Leaf. When you remove sub-nodes of a decision node, this process is called Pruning. The opposite of pruning is Splitting.

WebMar 25, 2024 · What Is Greedy Recursive Binary Splitting? In the binary splitting method, the tuples are split and each split cost function is calculated. The lowest cost split is selected. The splitting method is binary which is formed as 2 branches. It is recursive in nature as the same method (calculating the cost) is used for splitting the other tuples of ...
