Title:
PROBABILISTIC DATA MINING MODEL COMPARISON ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/045496
Kind Code:
A3
Abstract:
Comparison engine for comparing a first data mining model and a second data mining model is disclosed. A first data mining model M1 represents results of a first data mining task on a first data set D1 and provides a set of first prediction values. A second data mining model M2 represents results of a second data mining task on a second data set D2 and provides a set of second prediction values. A relation R is determined between said sets of prediction values. For at least a first record of an input data set, a first and second probability distribution is created based on the first and second data mining models applied to the first record, said probability distributions associating probabilities with said sets of prediction values.A distance measure d is calculated for said first record using the first and second probability distributions and the relation. At least one region of interest is determined based on said distance measure d.
