FUZZY LOGIC APPROACH IN DISEASE DIAGNOSIS - A REVIEW.

Abstract

In real world computing environment, the information is not complete, precise and certain, making very difficult to derive an actual decision. Medical Science is considered as a field of uncertainty, vagueness and complexity. An essential element of the medical profession is making numerous decisions. In this process doctors rely on gained knowledge and experience. However, it seems necessary for them to have the ability to think logically, to use reasoning, to infer, to precisely and clearly express their thoughts and justify the assertions made.  Fuzzy logic plays an important role in it. Detection of diseases in medical science is a very difficult task. To improve accuracy rate engineers helping in detection of the diseases by developing the Expert System using Fuzzy Logic. Fuzzy logic consists of many valued logic. It has varying values in the range of 0 and 1 instead of fix values. In this study, we will go through different diseases were fuzzy logic approach is advanced.
