Diagnose Headaches by Fuzzy Procedures

Yi-Fong Lin

Abstract: This paper is a response to the article of Ahn, Mun, Kim, Oh, and Han that was published in IEICE Transactions on Information and Systems, Volume E91-D, Number 4, APRIL 2008, 1215-1217. We will point out that their extension is based on the detailed data of knowing the frequency of three types such that their new occurrence information that was based on an intuitionistic fuzzy set for medical diagnosis of headache becomes redundant. We will advise researchers directly to use the detailed data to decide the diagnosis of headaches.
