Researchers have introduced the Cross-Head Attention Uplift Network (CHAUN) and a Robust Adversarial Inverse Propensity Score (RA-IPS) method to improve uplift modeling. CHAUN utilizes shared feature embeddings and cross-head attention to better model correlations between treatment and control groups. The RA-IPS method addresses scenarios where true propensity scores are unavailable by adversarially optimizing propensity weights. Experiments show CHAUN improves QINI scores by up to 25.6% and RA-IPS enhances robustness against unobserved confounding. AI
