Efficient mining of constrained correlated sets

Studies the problem of efficiently computing correlated item sets satisfying given constraints. We call them valid correlated item sets. It turns out that constraints can have subtle interactions with correlated item sets, depending on their underlying properties. We show that, in general, the set of minimal valid correlated item sets does not coincide with that of minimal correlated item sets that are valid, and we characterize classes of constraints for which these sets coincide. We delineate the meaning of these two spaces and give algorithms for computing them. We also give an analytical evaluation of their performance and validate our analysis with a detailed experimental evaluation
