Local fisher discriminant analysis
WitrynaLocal Fisher Discriminant Analysis (LFDA) is a linear dimension reduction method for supervised case, i.e., labels are given. It reflects local information to overcome undesired results of traditional Fisher Discriminant Analysis which results in a poor mapping when samples in a single class form form several separate clusters. Witryna1 sty 2006 · Therefore, the kernel local Fisher discriminant analysis (KLFDA) [18] takes the advantages of the Fisher discriminant analysis (FDA) [19] and locality preserving projections (LPP) [20] to overcome ...

Linear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.
