Classification: CPC G | IPC G

Claim 18:
19. A non-transitory computer readable medium storing therein instructions for controlling a programmable processor to discover or rank a change in a pattern of high-dimensional data, comprising:
instructions for determining a matrix representing a linear model of a dominant subspace for the high dimensional data;
instructions for iteratively optimizing a factorization of the matrix into an estimated feature basis matrix and an estimated indicator matrix corresponding to a set of principal angles representing the change in the pattern of the high dimensional data, with at least one automated processor;
instructions for determining a statistical likelihood ratio with respect to alternate hypotheses regarding a statistical significance of the change in the pattern of the high dimensional data based on sets of basis vectors determined dependent on the set of principal angles from the optimized factorization of the matrix;
instructions for, based on at least the statistical likelihood ratios, predicting the significant change represented in the high-dimensional data according to an adaptive criterion at least one of:
ranking the respective high dimensional data; and
determining a statistically significant difference of respective high dimensional data; and

instructions for altering the adaptive criterion dependent on the ranking or determined statistically significant difference.
