Interest Measures for Fuzzy Association Rules Based on Expectations of Independence
Michal Burda · Advances in Fuzzy Systems · 2014
Lift, leverage, and conviction are three of the best commonly known interest measures for crisp association rules. All of them are based on a comparison of observed support and the support that is expected if the antecedent and consequent part of the rule were stochastically independent. The aim of this paper is to provide a correct definition of lift, leverage, and conviction measures for fuzzy association rules and to study some of their interesting mathematical properties.
