The relationships, properties, and objects in the data generated from medical diagnosis and bioinformatics are fundamentally fuzzy. Fuzzy set theory is an ideal framework to deal with such data. Fuzzy set theory is considered to be an extended set theory to deal with uncertainty of boundary and classification. In this paper, we illustrate how fuzzy approaches based on fuzzy set theory can be applied to data in medical diagnostics and bioinformatics with various examples.
Keywords : Bioinformatics, fuzzy set theory, medical diagnosis, uncertainty.
