Decision tree classifier id3
WebID3 Decision Tree Algorithm. ID3 stands for Iterative Dichotomiser 3 and is named such because the algorithm iteratively (repeatedly) dichotomizes(divides) features into two or more groups at each step. It uses a top-down greedy approach to build a decision tree.

WebReviewer: Richard CHBEIR Iterative dichotomiser 3 (ID3) is a classification algorithm that uses a fixed set of examples to build a decision tree. This paper presents an interesting variant of the ID3 algorithm that can be used to classify vertically partitioned data while preserving the privacy of participated sites and parties.
