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,...
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...

it can determine the scale parameter automatically.This paper illustrates the proposed algorithm not only has inhibition for certain outliers but is able to cluster the data sets with different scales.Finally,experiments on both,artificial data and UCI data sets,show that the proposed method is ...
The conventional semantic image recognition and segmentation analysis are based on spectral clustering. According to the different image pixels, the input image is divided into two categories based on semantic analysis. Figure 1 presents the proposed method. Figure 1 Open in figure viewerPowerPoint ...
Abstract In recent years, with the great success of deep learning and especially deep unsupervised learning, many deep architectural clustering methods, collectively known as deep clustering, have e…
A novel approach is presented for synthetic aperture radar (SAR) image segmentation. By incorporating the advantages of maximally stable extremal regions (MSER) algorithm and spectral clustering (SC) method, the proposed approach provides effective and robust segmentation. First, the input image is tra...
