A Unified Framework for Representation-based Subspace Clustering of Out-of-sample and Large-scale Data
Xi Peng, Huajin Tang, Lei Zhang +2
Under the framework of spectral clustering, the key of subspace clustering is building a similarity graph which describes the neighborhood relations among data points. Some recent…

Inductive Sparse Subspace Clustering
Xi Peng, Lei Zhang, Zhang Yi
Sparse Subspace Clustering (SSC) has achieved state-of-the-art clustering quality by performing spectral clustering over a -norm based similarity graph. However, SSC is a…

Learning Locality-Constrained Collaborative Representation for Face Recognition
Xi Peng, Lei Zhang, Zhang Yi +1
The model of low-dimensional manifold and sparse representation are two well-known concise models that suggest each data can be described by a few characteristics. Manifold learnin…
