We present here a data mining technique for discovering all minimal non-trivial coarsest functional dependencies (FD) based on equivalence classes from similarity-based fuzzy relational databases. The similarity-based fuzzy data model has been ...
Knowledge discovery from databases copes with several problems including the heterogeneity of data and interpreting the solution in an understandable and convenient form for domain experts. Fuzzy logic approaches based on the computing ...
The problem of whether a given dependency in a database relation can be derived from a given set of dependencies is investigated. We show that the problem can be decided in polynomial time when the given set consists of either multivalued dependencies ...
