In the era of big data, many sparse linear discriminant analysis methods have been proposed for the classification and variable selection of the high-dimensional data. In order to solve the multiclass...
On BIC's Selection Consistency for Discriminant Analysis
BIC Discriminant Analysis Selection Consistency
2016/1/19
Linear and quadratic discriminant analysis are two very useful classification methods, for which the problem of variable selection is of fundamental impor-tance. To this end, a BIC-type selection crit...
Fisher linear discriminant analysis (LDA) can be sensitive to the problem data. Robust Fisher LDA can systematically alleviate the sensitivity problem by explicitly incorporating a model of data uncer...
Asymptotic Generalization Bound of Fisher's Linear Discriminant Analysis
Asymptotic Generalization Bound Fisher's Linear Discriminant Analysis
2012/9/17
Fisher’s linear discriminant analysis (FLDA) is an important dimension reduction method in sta-tistical pattern recognition. It has been shown that FLDA is asymptotically Bayes optimal under the homos...
A Direct Estimation Approach to Sparse Linear Discriminant Analysis
Classification constrained l1-minimization Fisher’s rule
2011/7/19
This paper considers sparse linear discriminant analysis of high-dimensional data. In contrast to the existing methods which are based on separate estimation of the precision matrix $\O$ and the diffe...

In many social, economical, biological and medical studies, one
objective is to classify a subject into one of several classes based on
a set of variables observed from the subject. Because the prob...

The so-called v-level grade discrimmant function is
introduced and its properties are investigated. In particular, its
distributions in class 1 and class 2 serve to characterize somc natural

The Discriminant Validity Of The Culture Assessment Instrument: A Comparison Of Company Cultures
Discriminant Validity The Culture Assessment Instrument Company Cultures
2009/5/18
The aim of this study was to assess the discriminant validity of the Culture Assessment Instrument (CAI); that is to distinguish between mean culture scores of different companies. The convenience sam...

2009/2/25
The problem of the non-robustness of the classical estimates in the setting of the
quadratic and linear discriminant analysis has been addressed by many authors:
Todorov et al. [19, 20], Chork and R...
