Research output: Contribution to journalArticle


An a posteriori approach to decision tree learning is proposed. The method, which reconstructs a decision tree during application to a real domain, preserves the previous error rate of diagnosis and frequency of diagnosis for the current tree. It also contains a scheme for eliminating the generation of pseudoexample sets to reduce computation time.
