In statistics, kernel Fisher discriminant analysis (KFD), also known as generalized discriminant analysis and kernel discriminant analysis, is a kernelized version of linear discriminant analysis (LDA). It is named after Ronald Fisher. WebSep 25, 2024 · Kernel Fisher discriminant analysis (KFD) provided by Baudat and Anouar and the generalized discriminant analysis (GDA) provided by Mika et al. are two independently developed approaches for kernel-based nonlinear extensions of discriminant coordinates. They are essentially equivalent.
