【Abstract】 Fuzzy-ID3 algorithm in the fuzzy decision tree is the fuzzy version of the ID3 algorithm proposed by Quinlan in 1986. The process of building trees is based on significant levelα , the value of αaffect the computation of fuzz y entropy and classification result of fuzzy decision tree in large degree. This paper analyzes the sensitivity of parameter αabout fuzzy entropy, expects to f ind qualitatively the analytic relationships between them, and provides the acad emic evidence of selecting parameter α in order to gain the best classification result更多还原
