1 When patterns occur in the form of groups generated by the same source, distinctions between sources can be exploited to improve accuracy. We present a method for exploiting such ‘style’ consistency using a quadratic discriminant. We show that under reasonable assumptions on the feature and class distributions, the estimation of style parameters is simple and accurate.

The present work studied 13 types of Chinese attitudes and compared the confusion patterns between subjective and objective identification. The listening experiment showed that the overall recognition rate for these attitudinal utterances was 46% by native subjects, while in discriminant analysis, the recognition rate was 25.4% based on five prosodic parameters (minimum f0, maximum f0, mean f0,...

Classes on creativity, innovation, and entrepreneurship are becoming quite popular at universities throughout the world. However, it is not easy for business students to get involved to innovative activities, especially patent application. The present study investigated how to enhance business students’ intention to participate in innovative activities and which incentives universities should c...

Abstract: This paper presents exploratory techniques for multivariate data, many of them well known to French statisticians and ecologists, but few well understood in North American culture. We present the general framework of duality diagrams which encompasses discriminant analysis, correspondence analysis and principal components, and we show how this framework can be generalized to the regre...

The purpose of this paper is to investigate the realization of the [nasal] contrast in French by performing an acoustic analysis of naturally spoken nasal and oral vowels, and by carrying out discriminant analysis on these data. Results consistently show that generic parametric representations allow to reliably discriminate between nasals and orals. A specific issue addressed in this paper is t...

in this study, by examining the character of the morphometric and meristic in which cyprinion macrostomus samples obtained from different locality in tigris, morphometric character which are transformed subject to discriminant analysis and depending on grouping model to number of discriminant functions and according to importance of these totally variance, morphogical variance among populations...

Background: The present study aimed to validate the thermal regions in Iran with an emphasis on the identification of the climatic cycles during the recent half-century. Methods: Data on daily temperature were extracted for 383 synoptic stations of Iran Meteorological Organization. For the zoning of the temperatures of Iran, multivariate statistical techniques (cluster analysis and discriminan...

In this paper we seek a Gaussian mixture model (GMM) of the classconditional densities for plug-in Bayes classification. We propose a method for setting the number of the components and the covariance matrices of the class-conditional GMMs. It compromises between simplicity of the model selection based on the Bayesian information criterion (BIC) and the high accuracy of the model selection base...
