ID3 (Quinlan 1986a), like candidate elimination, induces concepts from examples. It is particularly interesting for its representation of learned knowledge, its approach to the management of complexity, its heuristic for selecting candidate concepts, and its potential for handling noisy data. ID3 represents concepts as decision trees, a representation that
