Vertical Set Inner Product Technology (VSIP) with Predicate Trees
RFT-109, RFT-159
Vertical Set Inner Product Technology (VSIP) provides an order of magnitude speed-up to clustering numeric data (both full-space clustering and subspace clustering onto any subspace—including oblique subspaces) by providing a horizontal calculation across vertical predicate-tree datasets. The ability to scale the computations to very large data sets is the significant improvement over traditional methods. Can be used in conjunction with P-Tree (Peano count) models and associated algorithms for datamining applications.
