Some Applications of a Method of Identifying an Element of a Large Multidimensional Population.
Abstract
A method is proposed for comparing a target individual with those in a large file or library of individuals on the basis of certain measured characteristics. This method is based on the likelihood-ratio test of the hypothesis that the measured characteristics of the target and a candidate from the file correspond to independently selected individuals versus the alternative that they correspond to the same individual. Only candidates for which the likelihood ratio is very large are considered. Applications of this method to the identification of fingerprints, chemical compounds and medical records are discussed. The relevance of certain information numbers is pointed out and their application to the chemical compound problem illustrated.
