In today's computing era, data mining has been the one that turns all computing probable into possible, by means of prediction, description and understanding. For achieving it all, various data mining algorithms are being in use. Fuzzy in simple is a form of many valued logic and it's prominent for its wide applicability. This paper surveys the applications of fuzzy in data mining analysis. Put differently, fuzzy can be used for improving the efficiency otherwise for providing some kind of optimization to the process for achieving better results. Now it's straightforward to reveal that the data mining algorithms that are ambitious about fuzzy computing results in improved data analysis.
