01 Nov 1972TL;DR: It is shown that the maximization of the mean Bhattacharyya distance minimizes an upper bound on the error probability.
Abstract: A relationship between the probability of misrecognition and the expected Bhattacharyya distance is examined, and it is shown that the maximization of the mean Bhattacharyya distance minimizes an upper bound on the error probability.

TL;DR: In this paper, two types of characterizations of affinity and distance between two statistical populations are discussed, one based on a recurrence relation and the other dealing with a maximization principle.
Abstract: Matusita ([5]-[8]) introduced and discussed measures of 'aff ini ty ' and ' distance' between two statistical populations. This article is mainly concerned with two types of characterizations of 'aff ini ty ' and ' dist ance ' when the populations are discrete. One is based on a recurrence relation and the other deals with a maximization principle. By using the main results obtained in this article, characterization theorems are also given for Bhattacharyya's measure of distance ([1], [2]), Jeffreys' measure of invariance ([1], [3]), Pearson's measure of discrepancy [1] and a generalized measure of dispersion introduced by Mathai [4]. Alternate definitions of 'affinity ' and 'dis tance, ' as solutions of certain functional equations, are also suggested in this article. Consider two discrete distributions given by the probabilities,

TL;DR: This correspondence derives an upper bound on the probability of error of the m -class Bayes decision process when the patterns observed have first-order stochastic dependence.
Abstract: This correspondence derives an upper bound on the probability of error of the m -class Bayes decision process when the patterns observed have first-order stochastic dependence. The bound is derived by applying an information-theoretic approach in which both the equivocation and the Bhattacharyya coefficient play a role.

TL;DR: The use of high-resolution aeromagnetic surveys for detailed geologic mapping and mineral exploration is not yet common, nor are the flying and compilation techniques as standardized as those of conventional or lowsensitivity aerial magnetic surveys as discussed by the authors.
Abstract: The use of high‐resolution aeromagnetic surveys for detailed geologic mapping and mineral exploration is not yet common, nor are the flying and compilation techniques as standardized as those of conventional or lowsensitivity aeromagnetic surveys. Dr. Bhattacharyya has made a valuable contribution by presenting particularly interesting results and describing the techniques in some detail. But there are some points in his comparisons between high‐resolution and conventional surveys which could be misleading.
