决策树中ID3算法的研究
Research of ID3 algorithm in decision tree
摘要
Abstract
ID3 algorithm was the core approach in Decision Tree algorithm. In this paper, basic ideas,approaches and performance of ID3 algorithm were introduced and analyzed, and some deficiencies were found. Then weight was introduced in the research in order to improve the algorithm. Results of the experiments show that improvement involving weight factors are effective.关键词
