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. WebGeneral Structure of Hunt’s Algorithm Let Dt be the set of training recordsthat reach a node t. General procedure: – If Dt contains records thatbelong the same class y t, then t is a leaf node labeled as y t. – If Dt contains records thatbelong to more than one class,use an attribute test to split thedata into smaller subsets.
