A General Causal Inference Framework for Cross-Sectional Observational Data

no code implementations28 Apr 2024 Yonghe Zhao, Huiyan Sun

Therefore, this paper proposes a General Causal Inference (GCI) framework specifically designed for cross-sectional observational data, which precisely identifies the key confounding covariates and provides corresponding identification algorithm.

Does Misclassifying Non-confounding Covariates as Confounders Affect the Causal Inference within the Potential Outcomes Framework?

no code implementations22 Aug 2023 Yonghe Zhao, Qiang Huang, Shuai Fu, Huiyan Sun

Most causal inference models based on the POF (CIMs-POF) are designed for eliminating confounding bias and default to an underlying assumption of Confounding Covariates.

VLUCI: Variational Learning of Unobserved Confounders for Counterfactual Inference

no code implementations2 Aug 2023 Yonghe Zhao, Qiang Huang, Siwei Wu, Yun Peng, Huiyan Sun

By disentangling observed and unobserved confounders, VLUCI constructs a doubly variational inference model to approximate the distribution of unobserved confounders, which are used for inferring more accurate counterfactual outcomes.

De-confounding Representation Learning for Counterfactual Inference on Continuous Treatment via Generative Adversarial Network

no code implementations24 Jul 2023 Yonghe Zhao, Qiang Huang, Haolong Zeng, Yun Pen, Huiyan Sun

Extensive experiments on synthetic datasets show that the DRL model performs superiorly in learning de-confounding representations and outperforms state-of-the-art counterfactual inference models for continuous treatment variables.

A General Unified Graph Neural Network Framework Against Adversarial Attacks

no code implementations29 Sep 2021 Yujie Gu, Yangkun Cao, Qiang Huang, Huiyan Sun

The other is the convolution operation for features to find the optimal solution adopting the Laplacian smoothness and the prior knowledge that nodes with many neighbors are difficult to attack.
