Multi-View Spectral Clustering via ELM-AE Ensemble Features Representations Learning

open access: yesIEEE Access, 2020
Spectral cluster based on multi-view data has proven effective for clustering multi-source real-world data because consensus and complementary information of multi-view data ensure the result of clustering.

Federated Multi-View Spectral Clustering

open access: yesIEEE Access, 2020
Multi-view spectral clustering (MVSC) has become a popular approach to harvest knowledge about group information from multiple views of data, owned by different parties. A high quality MVSC approach usually requires collecting massive amount of data from

PolSAR Image Classification Method Based on Markov Discriminant Spectral Clustering

open access: yesLeida xuebao, 2019
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.

Accelerated Spectral Clustering Using Graph Filtering Of Random Signals [PDF]

open access: yes, 2015
We build upon recent advances in graph signal processing to propose a faster spectral clustering algorithm. Indeed, classical spectral clustering is based on the computation of the first k eigenvectors of the similarity matrix' Laplacian, whose ...

Mini-batch spectral clustering [PDF]

open access: yes2017 International Joint Conference on Neural Networks (IJCNN), 2017
The cost of computing the spectrum of Laplacian matrices hinders the application of spectral clustering to large data sets. While approximations recover computational tractability, they can potentially affect clustering performance. This paper proposes a practical approach to learn spectral clustering based on adaptive stochastic gradient optimization.

Consistency of spectral clustering in stochastic block models [PDF]

open access: yes, 2014
We analyze the performance of spectral clustering for community extraction in stochastic block models. We show that, under mild conditions, spectral clustering applied to the adjacency matrix of the network can consistently recover hidden communities ...
