1) Course is Computers in BioMedicine

In about 250 words , Discuss Use of fuzzy logic in biomedical expert systems and diagnosis.

Answer 1

Fuzzy Logic in bio medical expert systems and diagnosis:

Medical practitioners have different logical ability and decision-making capability so, a kind of variation in decision making is seen among them this is also because of their approaches to deal with uncertainties in knowledge and information. The decision making during diagnostic also depends on the experience, expertise and perception of the practitioners. Mistake may happen during diagnosis if the system is more complex.

Fuzzy logic provides us with the powerful methods of reasoning that are capable of handling these uncertainties and vagueness. Fuzzy logic is an amazing tool for building intelligent decision-making systems which is based on the knowledge and observation of experts.

Since human reasoning and decision making is fuzzy in nature i.e., imprecise or inexact and also involves high degree of vagueness and in evidence and concept utilization and requires a high level of uncertainty management in medical diagnosis. Numerous fuzzy expert system has been proposed by researchers to deal with this vagueness and complexities and they have also offered practical aids to users in form of fuzzy expert system.

These expert systems are designed for specific disease and hence these provide support on decision process for these specific diseases. The computer based diagnostic tools and knowledge base certainly helps for early diagnosis of diseases. Some of the areas in which fuzzy logic are used to develop diversified application are fuzzy model for illness, Heart and cardiovascular disease diagnosis, malaria diagnosis , diabetes diagnosis and treatment etc. These support system for diagnostic purposes of human diseases has helped practitioners as well as patients to greater extent.
