Decision Trees in Python – Step-By-Step Implementation

The ID3 algorithm begins with the original set as the root node. On each iteration of the algorithm, it iterates through every unused attribute of the set and calculates the entropy or the information gain of that attribute. It then selects the attribute which has the smallest entropy (or largest information gain) value. The set is then split or partitioned by the selected attribute to produce subsets of th… WebDifferent Decision Tree algorithms are explained below −. ID3. It was developed by Ross Quinlan in 1986.
