Web6 feb. 2024 · Kernel Fisher discriminant (KFD) is a popular tool as a nonlinear extension of Fisher's linear discriminant, based on the use of the kernel trick. However, its asymptotic properties are still rarely studied. We first present an operator-theoretical formulation of KFD which elucidates the population target of the estimation problem. … 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. Meer weergeven Intuitively, the idea of LDA is to find a projection where class separation is maximized. Given two sets of labeled data, $${\displaystyle \mathbf {C} _{1}}$$ and $${\displaystyle \mathbf {C} _{2}}$$, we can … Meer weergeven The extension to cases where there are more than two classes is relatively straightforward.
