Embodiment Construction
[0046] 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.
[0047] 1. Multi-core k-means algorithm (MKKM)
[0048] Represents a collection of n samples, Indicates that the pth feature is matched by x to a regenerated kernel Hilbert space In a multi-core configuration, each sample has multiple feature representations, which are represented by a set of feature maps Defined. Specifically, each sample is denoted as φ β (x)=[β 1 φ 1 (x) T ,...,β m φ m (x) T ] T , where β=[β 1 ,...,β m ] T , representing the coefficients of the m base kernels. These coefficients will be optimized during the learning process. Based on the definit...
