Medical Applications with Fuzzy Sets

Abstract

This tutorial paper presents a treatment of linguistic entities in medicine, allowing the assignment of graded diagnoses or types to patients. A knowledge base can consist of a tableau with linguistic entries or of a set of propositions within rules and, in both cases, relationships between attributes like plasma lipids, serum proteins, and diagnoses or types, are not expressed by numbers but by labels of fuzzy sets. Possibility distributions and fuzzy intervals are simply introduced to give a meaning to the fuzzy propositions issued from the knowledge base. Finally, it is shown how possibility measures can be used to assign different types to patients after examination of their condition.
