Abstract

The embodiment of the invention discloses a subspace clustering method, device and equipment based on multiple views and a computer readable storage medium. The method comprises the following steps of: estimating a rank function by taking a kernel norm and a Forbenius norm of a combined matrix as regular terms based on an extracted data characteristic matrix of multi-view data, and introducing tensor constraint to construct an optimization objective function of subspace clustering of each view matrix; Solving an optimization problem of the optimization objective function to obtain a subspace representation matrix of each view; performing Calculating to obtain an affinity matrix of the multi-view data based on the subspace representation matrix of each view; And segmenting the affinity matrix by using a spectral clustering algorithm to realize multi-view subspace clustering. According to the method and the device, high-order correlation information among multiple views is fully utilized, so that the clustering precision of the multi-view data is favorably improved; The kernel norm union and the Forbenius norm of the matrix are used as regular terms to estimate the rank function, sothat the robustness of the algorithm is improved, and the multi-view data clustering performance is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of pattern recognition computing, and in particular to a multi-view-based subspace clustering method, device, equipment, and computer-readable storage medium. Background technique [0002] With the rapid development of information science technology and artificial intelligence technology, pattern recognition is used to process and analyze various forms of (numerical, textual and logical) information representing things or phenomena, so as to realize the recognition of things or phenomena. Describe, identify, classify and explain, and develop accordingly. [0003] Multi-view data widely appears in many application fields. For example, in the field of natural language processing, a document or the entire corpus may have multilingual versions. Each language version is actually a representation of the document, such as machine Parallel corpora in the field of translation. In the field of image retr...
