Online Prediction of Extreme Conditional Quantiles via B-Spline Interpolation
Zhengpin Li, Jian Wang, Yanxi Hou
Extreme quantiles are critical for understanding the behavior of data in the tail region of a distribution. It is challenging to estimate extreme quantiles, particularly when deali…
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…
