A robust optimal control problem with moment constraints on distribution: theoretical analysis and an algorithm
Jianxiong Ye, Lei Wang, Changzhi Wu +3
We study an optimal control problem in which both the objective function and the dynamic constraint contain an uncertain parameter. Since the distribution of this uncertain paramet…
Exploiting Structure Sparsity for Covariance-based Visual Representation
Jianjia Zhang, Lei Wang, Luping Zhou +1
The past few years have witnessed increasing research interest on covariance-based feature representation. A variety of methods have been proposed to boost its efficacy, with some…
OPML: A One-Pass Closed-Form Solution for Online Metric Learning
Wenbin Li, Yang Gao, Lei Wang +3
To achieve a low computational cost when performing online metric learning for large-scale data, we present a one-pass closed-form solution namely OPML in this paper. Typically, th…
Directional Generation of Graphene Plasmons by Near Field Interference
Lei Wang, Wei Cai, Xinzheng Zhang +2
The highly unidirectional excitation of graphene plasmons (GPs) through near-field interference of orthogonally polarized dipoles is investigated. The preferred excitation directio…
Compositional Model based Fisher Vector Coding for Image Classification
Lingqiao Liu, Peng Wang, Chunhua Shen +4
Deriving from the gradient vector of a generative model of local features, Fisher vector coding (FVC) has been identified as an effective coding method for image classification. Mo…
