Abstract:Abstract-In the recent years, there has been significant development in the field of Probabilistic Frequent Itemset Mining (PFIM). Despite the complexity of calculating the frequentness probability of an itemset, approximation techniques allow us to reduce the complexity of the problem with very low approximation error. In this paper we investigate how to incorporate hierarchical taxonomies into the attribute uncertainty model, which assumes independence between the existential probability of items in a trans… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
