Sparse Subspace Clustering via Group Sparse Coding
MetadataShow full item record
We propose in this paper a novel sparse subspace clustering method that regularizes sparse subspace representation by exploiting the structural sharing between tasks and data points via group sparse coding. We derive simple, provably convergent, and computationally efificient algorithms for solving the proposed group formulations. We demonstrate the advantage of the framework on three challenging benchmark datasets ranging from medical record data to image and text clustering and show that they consistently outperform rival methods.

Zhang, X.; Pham, DucSon; Phung, D.; Liu, Wan-Quan; Saha, B.; Venkatesh, S. (2015)Many vision problems deal with high-dimensional data, such as motion segmentation and face clustering. However, these high-dimensional data usually lie in a low-dimensional structure. Sparse representation is a powerful ...
Zhang, X.; Phung, D.; Venkatesh, S.; Pham, DucSon; Liu, Wan-Quan (2016)In many real-world computer vision applications, such as multi-camera surveillance, the objects of interest are captured by visual sensors concurrently, resulting in multi-view data. These views usually provide complementary ...
