Continual Causal Inference with Incremental Observational Data

no code implementations3 Mar 2023 Zhixuan Chu, Ruopeng Li, Stephen Rathbun, Sheng Li

We propose a Continual Causal Effect Representation Learning method for estimating causal effects with observational data, which are incrementally available from non-stationary data distributions.

DRGCN: Dynamic Evolving Initial Residual for Deep Graph Convolutional Networks

1 code implementation10 Feb 2023 Lei Zhang, Xiaodong Yan, Jianshan He, Ruopeng Li, Wei Chu

Our experimental results show that our model effectively relieves the problem of over-smoothing in deep GCNs and outperforms the state-of-the-art (SOTA) methods on various benchmark datasets.

ESCM$^2$: Entire Space Counterfactual Multi-Task Model for Post-Click Conversion Rate Estimation

1 code implementation3 Apr 2022 Hao Wang, Tai-Wei Chang, Tianqiao Liu, Jianmin Huang, Zhichao Chen, Chao Yu, Ruopeng Li, Wei Chu

In this paper, we theoretically demonstrate that ESMM suffers from the following two problems: (1) Inherent Estimation Bias (IEB), where the estimated CVR of ESMM is inherently higher than the ground truth; (2) Potential Independence Priority (PIP) for CTCVR estimation, where there is a risk that the ESMM overlooks the causality from click to conversion.
