Correlation synthetic discriminant functions

Applied Optics, 1986
Advanced filters are described for distortion-invariant space-invariant object identification and location in clutter using correlators. These correlation synthetic discriminant functions (SDFs) are extensions of earlier projection SDFs. They provide control of the sidelobe levels and the shape of the output correlation function as well as its peak ...

Discriminative Learning Quadratic Discriminant Function for Handwriting Recognition

IEEE Transactions on Neural Networks, 2004
In character string recognition integrating segmentation and classification, high classification accuracy and resistance to noncharacters are desired to the underlying classifier. In a previous evaluation study, the modified quadratic discriminant function (MQDF) proposed by Kimura et al. was shown to be superior in noncharacter resistance but inferior

Functions on Discriminants

Journal of the London Mathematical Society, 1984
In what follows k denotes the field of real or complex numbers. If \(D,0\subset k^ p\), 0 is the discriminant variety of the versal unfolding of an analytic function germ \(f: k^ n,0\to k,0\), it is of some interest to classify smooth functions h: D,0\(\to k,0.\) In Commun.

Discriminant Function Analysis

2001
The aim of cluster analysis, the subject of the previous chapter, is to discover whether multivariate data contains relatively distinct groups of observations. A further aspect of the classification of multivariate data concerns the derivation of rules and procedures for allocating individuals to one of a set of a priori defined groups in some optimal ...

Functional Discriminant Coordinates

Communications in Statistics - Theory and Methods, 2014
In this article we propose a new method of construction of discriminant coordinates and their kernel variant based on the regularization (ridge regression). Moreover, we compare the case of discriminant coordinates, functional discriminant coordinates and the kernel version of functional discriminant coordinates on 20 data sets from a wide variety of ...
