In this paper, we introduce a modified version of linear discriminant analysis, called the "shrunken centroids regularized discriminant analysis" (SCRDA). This method generalizes the idea of the "nearest shrunken centroids" (NSC) (Tibshirani and others, 2003) into the classical discriminant analysis. The SCRDA method is specially designed for classification problems in high dimension low sample...

In this paper a lexicon driven segmentationrecognition scheme for unconstrained Bangla handwritten word recognition is proposed for Indian postal automation. In the proposed method, at first, binarization of the input document is done and slant correction of the individual words is performed. Next, using water reservoir concept words are pre-segmented into possible primitive components (charact...

In this paper, we introduce a family of some modified versions of linear discriminant analysis, called “shrunken centroids regularized discriminant analysis” (SCRDA). These methods generalize the idea of the nearest shrunken centroids of Prediction Analysis of Microarray (PAM) into the classical discriminant analysis. These SCRDA methods are specially designed for classification problems in hig...

The application of supervised learning machines trained to minimize the Cross-Entropy error to radar detection is explored in this article. The detector is implemented with a learning machine that implements a discriminant function, which output is compared to a threshold selected to fix a desired probability of false alarm. The study is based on the calculation of the function the learning mac...

Discriminant analysis is applied to the problem of recognition 5'-, internal and 3'-exons in human DNA sequences. Specific recognition functions were developed for revealing exons of particular types. The method based on a splice site prediction algorithm that uses the linear Fisher discriminant to combine the information about significant triplet frequencies of various functional parts of spli...

Capsule Discriminant functions based on morphometric variables provide a reliable method for sex identification of free-living and hacked young Ospreys. Aims To describe an easy, accurate and low-cost method for sex determination of fully grown nestling and fledgling Ospreys Pandion haliaetus based on morphometric measurements. Methods Four different measurements were taken in 114 birds (40–73 ...

—Sexual size dimorphism and determination of sex in Atlantic yellow-legged gulls Larus michahellis lusitanius from Northern Spain. Aims: We evaluate sexual size dimorphism in Atlantic yellow-legged gulls Larus michahellis lusitanius and provide a discriminant function to sex gulls in hand. Location: Two islands of the Basque Country (Northern Spain). Methods: Incubating gulls were trapped, band...

According to Hermite there exists only a finite number of number fields having a given degree, and a given value of the discriminant, nevertheless this number is not known generally. The determination of a maximum number of number fields of degree 10 having a given discriminant that contain a subfield of degree 5 having a fixed class number, narrow class number and Galois group is the purpose o...
