Image segmentation by selecting eigenvectors based on extended information entropy
For spectral clustering algorithm, the quality of eigenvectors of graph affinity matrix is very important for the clustering result. So, how to obtain high‐quality eigenvectors is crucial.

SACOC: A spectral-based ACO clustering algorithm [PDF]
The application of ACO-based algorithms in data mining is growing over the last few years and several supervised and unsupervised learning algorithms have been developed using this bio-inspired approach. Most recent works concerning unsupervised learning

PolSAR Image Classification Method Based on Markov Discriminant Spectral Clustering
Due to the existing spectral clustering methods have low accuracy for PolSAR image classification, a Markov-based Discriminative Spectral Clustering(MDSC) method is proposed, which has the characteristics of low-rank and sparse decomposition.

Density Gain-Rate Peaks for Spectral Clustering
Clustering has been troubled by varying shapes of sample distributions, such as line and spiral shapes. Spectral clustering and density peak clustering are two feasible techniques to address this problem, and have attracted much attention from academic ...

Scalable Spectral Clustering With Nyström Approximation: Practical and Theoretical Aspects
Spectral clustering techniques are valuable tools in signal processing and machine learning for partitioning complex data sets. The effectiveness of spectral clustering stems from constructing a non-linear embedding based on creating a similarity graph ...

On spectral clustering, informativeness and seriation
Brockmeier, Austin J.This thesis studies spectral clustering and seriation, which have very similar relaxed objective functions. We analyzed these problems from the standpoint of informativeness, an unsupervised measure of the similarity within a data ...

Spectral camera clustering [PDF]
We propose an algorithm for clustering large sets of images of a scene into smaller subsets covering different parts of the scene suitable for 3D reconstruction. Unlike the canonical view selection of [13], we do not focus only on the visibility information, but introduce an alternative similarity measure which takes into account the relative camera ...

Newtonian Spectral Clustering [PDF]
In this study we propose a systematic methodology for constructing a sparse affinity matrix to be used in an advantageous spectral clustering approach. Newton's equations of motion are employed to concentrate the data points around their cluster centers, using an appropriate potential.

Constrained spectral clustering based methodology for intentional controlled islanding of large-scale power systems [PDF]
Intentional controlled islanding is an effective corrective approach to minimise the impact of cascading outages leading to large-area blackouts. This study proposes a novel methodology, based on `constrained spectral clustering', that is computationally
