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…
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…
