Researchers have developed a new doubly robust causal effect estimator tailored for post-click conversion rate (CVR) prediction. This method addresses sample selection bias and variance issues inherent in existing causal inference techniques when applied to clicked samples. The proposed framework utilizes targeted regularization for improved numerical stability and practical application, achieving a faster convergence rate than nuisance parameter estimation, even with flexible non-parametric estimators like neural networks. Experiments on synthetic and real-world data confirm its effectiveness and robustness, outperforming methods that combine loss debiasing with standard causal estimators. AI
