Fast Graph Subset Selection Based on G-optimal Design
Zhengpin Li, Zheng Wei, Jian Wang +2
Graph sampling theory extends the traditional sampling theory to graphs with topological structures. As a key part of the graph sampling theory, subset selection chooses nodes on g…
SAM: A Self-adaptive Attention Module for Context-Aware Recommendation System
Jiabin Liu, Zheng Wei, Zhengpin Li +4
Recently, textual information has been proved to play a positive role in recommendation systems. However, most of the existing methods only focus on representation learning of text…
One-Bit Matrix Completion with Differential Privacy
Zhengpin Li, Zheng Wei, Zengfeng Huang +2
As a prevailing collaborative filtering method for recommendation systems, one-bit matrix completion requires data collected by users to provide personalized service. Due to insidi…
Applying Differential Privacy to Tensor Completion
Zheng Wei, Zhengpin Li, Xiaojun Mao +1
Tensor completion aims at filling the missing or unobserved entries based on partially observed tensors. However, utilization of the observed tensors often raises serious privacy c…
Compressive Sensing Approaches for Sparse Distribution Estimation Under Local Privacy
Zhongzheng Xiong, Jialin Sun, Xiaojun Mao +3
Recent years, local differential privacy (LDP) has been adopted by many web service providers like Google \cite{erlingsson2014rappor}, Apple \cite{apple2017privacy} and Microsoft \…
ADCC: An Effective and Intelligent Attention Dense Color Constancy System for Studying Images in Smart Cities
Yilang Zhang, Neal N. Xiong, Zheng Wei +2
As a novel method eliminating chromatic aberration on objects, computational color constancy has becoming a fundamental prerequisite for many computer vision applications. Among al…
