Clustering transactions using large items
CIKM '99: Proceedings of the eighth international conference on Information and knowledge managementNovember 1999, Pages 483–490https://doi.org/10.1145/319950.320054In traditional data clustering, similarity of a cluster of objects is measured by pairwise similarity of objects in that cluster. We argue that such measures are not appropriate for transactions that are sets of items. We propose the notion of large ...
