Identifying Causal Effects under Kink Setting: Theory and Evidence

no code implementations14 Apr 2024 Yi Lu, Jianguo Wang, Huihua Xie

This paper develops a generalized framework for identifying causal impacts in a reduced-form manner under kinked settings when agents can manipulate their choices around the threshold.

A Survey of Learned Indexes for the Multi-dimensional Space

no code implementations11 Mar 2024 Abdullah Al-Mamun, Hao Wu, Qiyang He, Jianguo Wang, Walid G. Aref

We present a taxonomy that classifies and categorizes each learned multi-dimensional index, and survey the existing literature on learned multi-dimensional indexes according to this taxonomy.

SUREL+: Moving from Walks to Sets for Scalable Subgraph-based Graph Representation Learning

1 code implementation6 Mar 2023 Haoteng Yin, Muhan Zhang, Jianguo Wang, Pan Li

Subgraph-based graph representation learning (SGRL) has recently emerged as a powerful tool in many prediction tasks on graphs due to its advantages in model expressiveness and generalization ability.
