Two-weight and three-weight linear codes based on Weil sums
Gaopeng Jian
Linear codes with few weights have applications in secret sharing, authentication codes, association schemes and strongly regular graphs. In this paper, several classes of two-weig…
A Unified Convex Surrogate for the Schatten- Norm
Chen Xu, Zhouchen Lin, Hongbin Zha
The Schatten- norm () has been widely used to replace the nuclear norm for better approximating the rank function. However, existing methods are either 1) not scalable fo…
Accelerated Alternating Direction Method of Multipliers: an Optimal Nonergodic Analysis
Huan Li, Zhouchen Lin
The Alternating Direction Method of Multipliers (ADMM) is widely used for linearly constrained convex problems. It is proven to have an nonergodic convergence rate…
Globally Variance-Constrained Sparse Representation and Its Application in Image Set Coding
Xiang Zhang, Jiarui Sun, Siwei Ma +4
Sparse representation leads to an efficient way to approximately recover a signal by the linear composition of a few bases from a learnt dictionary, based on which various successf…
Graph Construction with Label Information for Semi-Supervised Learning
Liansheng Zhuang, Zihan Zhou, Jingwen Yin +4
In the literature, most existing graph-based semi-supervised learning (SSL) methods only use the label information of observed samples in the label propagation stage, while ignorin…
Subspace Clustering Based Tag Sharing for Inductive Tag Matrix Refinement with Complex Errors
Yuqing Hou, Zhouchen Lin, Jin-ge Yao
Annotating images with tags is useful for indexing and retrieving images. However, many available annotation data include missing or inaccurate annotations. In this paper, we propo…
