Abstract:
A program storage device tangibly embodying a program of instructions executable by a machine to perform a method for transforming components of descriptor vectors that characterize molecular complexes, wherein said descriptor vectors are classified into groups, said method comprising:generating first data representing differences between said groups of descriptor vectors; generating second data representing variation within said groups of said descriptor vectors; identifying a set of component vectors that maximizes an F distributed criterion function, said criterion function having a numerator based upon said first data and a denominator based upon said second data; generating an F distributed statistic for subsets of said component vectors, said statistic having a numerator based upon said first data and a denominator based upon said second data; for each particular subset of component vectors, calculating a probability value for the F-distributed statistic associated with the particular subset; selecting a probability value from probability values for said subsets of component vectors based upon a predetermined criterion; identifying the subset of said component vectors associated with the selected probability value; and for at least one descriptor vector for the molecular complexes, mapping said at least one descriptor vector to a space corresponding to the subset of component vectors associated with the selected probability value for subsequent processing.
