Rules discovery in fuzzy relational databases
Juan-Carlos Cubero, Olga Pons, Juan Miguel Medina, M.A. Vila · 2002
We are concerned with the problem of defining a fuzzy dependency in the framework of a fuzzy relational database. Of prime interest is the development of a fuzzy algebra operator, which allows us to store that information in a separated relation with fewer tuples. Its definition can be carried out through a crisp criterion or through a fuzzy one: we study the necessary restrictions for each case.
