In this paper, we present a simple spectral clustering algorithm that can be implemented using a few lines of Matlab. Using tools from matrix perturbation theory, we analyze the algorithm, and give conditions under which it can be expected to do well. We also show surprisingly good experimental...

This paper introduces CABGSI, a novel graph-based clustering algorithm that effectively addresses the limitations of traditional clustering techniques. Unlike conventional methods that require predefined cluster quantities and assume simple geometrical data structures, CABGSI leverages graph structural entropy to...
The proposed algorithm makes full use of the excellent performance of spectral clustering as well as avoids the selection of the accurate parameter in spectral clustering. Experiments show that compared with other common cluster ensemble techniques, the proposed algorithm is more excellent and efficient,...

Spectral clustering for image segmentation is difficult to calculate the spectrum of weighted matrix. A multistage sampling spectrum image clustering algorithm was designed to eliminate it. First, the sampling theorem was given and proved, and the minimum sample size was derived according to the smalle...
Spectral clustering is a newly emerged effective and widely used clustering method.With the essence of initialization sensitivity in spectral clustering,the global K-means clustering algorithm was introduced.Then a spectral clustering algorithm based on global K-means was proposed.Compared with the traditi...
Analysing the defect on different similarity matrix in spectral clustering, we propose a new algorithm—Spectral clustering algorithm based on K-nearest neighbor measure. The K-nearest neighbor measure focuses on using data points between the common number of nearest neighbors to measure the degree of...
