Diverse Dimension Decomposition of an Itemset Space

Abstract: We introduce the problem of diverse dimension decomposition in transactional databases. A dimension is a set of mutually-exclusive itemsets, and our problem is to find a decomposition of the itemset space into dimensions, which are orthogonal to each other, and that provide high coverage of the input database. The mining framework we propose effectively represents a dimensionality-reducing transformation from the space of all items to the space of orthogonal dimensions. Our approach relies on information-theor… Show more
