Hierarchical kernel spectral clustering
Web1 de fev. de 2024 · Note that while the Gaussian-kernel is used as example, the spectral clustering is also applicable to other types of kernel. The weight can thus be normalized as (2) w i j = p i j / ( d i d j ) The normalized weight matrix can be written as W = D − 1 2 P D − 1 2 , where D is a diagonal matrix with entries d i = ∑ j p i j .
