Private graphon estimation via sum-of-squares

no code implementations18 Mar 2024 Hongjie Chen, Jingqiu Ding, Tommaso d'Orsi, Yiding Hua, Chih-Hung Liu, David Steurer

We develop the first pure node-differentially-private algorithms for learning stochastic block models and for graphon estimation with polynomial running time for any constant number of blocks.

Hierarchical Multi-Interest Co-Network For Coarse-Grained Ranking

no code implementations19 Oct 2022 Xu Yuan, Chen Xu, Qiwei Chen, Tao Zhuang, Hongjie Chen, Chao Li, Junfeng Ge

This paper proposes a Hierarchical Multi-Interest Co-Network (HCN) to capture users' diverse interests in the coarse-grained ranking stage.

On the well-spread property and its relation to linear regression

no code implementations16 Jun 2022 Hongjie Chen, Tommaso d'Orsi

In this paper, we show that there exists a family of design matrices lacking well-spreadness such that consistent recovery of the parameter vector in the above robust linear regression model is information-theoretically impossible.

A Context Integrated Relational Spatio-Temporal Model for Demand and Supply Forecasting

no code implementations25 Sep 2020 Hongjie Chen, Ryan A. Rossi, Kanak Mahadik, Hoda Eldardiry

We propose a novel context integrated relational model, Context Integrated Graph Neural Network (CIGNN), which leverages the temporal, relational, spatial, and dynamic contextual dependencies for multi-step ahead demand forecasting.
