ファジィ測度を用いた診断支援システム : λ-ファジィ測度を用いた鑑別システム(一般講演-診断-)

抄録

This paper presents a construction method for a diagnostic support system using a fuzzy measure and application of the method. λ-fuzzy measure is employed as a measure of items for evaluating disease. Choquet's integral is utilized for evaluation of disease. The density of the fuzzy measure and λ is detected by a genetic algorithm for constructing the fuzzy system. This method was applied to construction of an endoscopic diagnostic support system of depressed type early gastric carcinoma. As a result, the λ-fuzzy measure reflects the measure of the doctor's subjectivity and the accuracy is more than 93%. The result indicates that our method has applicabilty for constructing system using a λ-fuzzy measure.
