Deep Representation of Facial Geometric and Photometric Attributes for Automatic 3D Facial Expression Recognition
Huibin Li, Jian Sun, Dong Wang +2
In this paper, we present a novel approach to automatic 3D Facial Expression Recognition (FER) based on deep representation of facial 3D geometric and 2D photometric attributes. A…
Sparse Index Tracking Based On Model And Algorithm
Fengmin Xu, Zongben Xu, Honggang Xue
Recently, regularization have been attracted extensive attention and successfully applied in mean-variance portfolio selection for promoting out-of-sample properties and decr…
An Efficient Optimization Approach for a Cardinality-Constrained Index Tracking Problem
Fengmin Xu, Zhaosong Lu, Zongben Xu
In the practical business environment, portfolio managers often face business-driven requirements that limit the number of constituents in their tracking portfolio. A natural index…
Re-scale AdaBoost for Attack Detection in Collaborative Filtering Recommender Systems
Zhihai Yang, Lin Xu, Zhongmin Cai
Collaborative filtering recommender systems (CFRSs) are the key components of successful e-commerce systems. Actually, CFRSs are highly vulnerable to attacks since its openness. Ho…
Shrinkage degree in -re-scale boosting for regression
Lin Xu, Shaobo Lin, Yao Wang +1
Re-scale boosting (RBoosting) is a variant of boosting which can essentially improve the generalization performance of boosting learning. The key feature of RBoosting lies in intro…
Learning a Convolutional Neural Network for Non-uniform Motion Blur Removal
Jian Sun, Wenfei Cao, Zongben Xu +1
In this paper, we address the problem of estimating and removing non-uniform motion blur from a single blurry image. We propose a deep learning approach to predicting the probabili…
Model selection of polynomial kernel regression
Shaobo Lin, Xingping Sun, Zongben Xu +1
Polynomial kernel regression is one of the standard and state-of-the-art learning strategies. However, as is well known, the choices of the degree of polynomial kernel and the regu…
Total Variation Regularized Tensor RPCA for Background Subtraction from Compressive Measurements
Wenfei Cao, Yao Wang, Jian Sun +4
Background subtraction has been a fundamental and widely studied task in video analysis, with a wide range of applications in video surveillance, teleconferencing and 3D modeling.…
Video Primal Sketch: A Unified Middle-Level Representation for Video
Zhi Han, Zongben Xu, Song-Chun Zhu
This paper presents a middle-level video representation named Video Primal Sketch (VPS), which integrates two regimes of models: i) sparse coding model using static or moving primi…
