Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0040] 1. Kernel k-means clustering (KKM)
[0041] Represents a set of n samples, Represents a feature map that maps x to a regenerated kernel Hilbert space The objective function of kernel k-means clustering is to minimize the kernel alignment matrix Z ∈ {0, 1} n×k The sum of squares loss can be expressed as the following optimization problem:
[0042]
[0043] in, and Represent the size and center of the cth cluster, 1≤c≤k, respectively.
[0044] The optimization problem described by equation (1) can be written in the following matrix-vector form:
