Web09. maj 2024. · Classification by discriminant analysis. Let’s see how LDA can be derived as a supervised classification method. Consider a generic classification problem: A random variable X comes from one of K classes, with some class-specific probability densities f(x).A discriminant rule tries to divide the data space into K disjoint regions that represent all … Weband 3 we introduce the Grassmann manifolds and de-rive various distances on the space. In Sec. 4 we present a kernel view of the problem and emphasize the advantages of using positive deﬁnite metrics. In Sec. 5 we propose the Grassmann Discriminant Analysis and compare it with other subspace-based discrimination methods.
