WebThe following is a recursive definition of Hunt’s algorithm. The general recursive procedure is defined as below: 1. If D t contains records that belong the same class y t , then t is a leaf node labeled as y t 2. If D t is an empty set, then t is a … WebOne such algorithm is Hunt’s algorithm, which is the basis of many existing de- cision tree induction algorithms, including ID3, C4.5, and CART. This section presents a high-level discussion of Hunt’s algorithm and illustrates some of its design issues. boilersmith
