ECUP and NLGR: Context-Aware Uplift Modeling and Reranking for Meituan Aggregation Page Ads

The paper introduces ECUP, a context‑enhanced uplift‑modeling framework that mitigates chain bias and treatment mismatch through a full‑chain enhancement network, task‑enhanced priors, and bit‑level treatment adaptation, achieving superior AUUC and QINI scores and online A/B gains for Meituan’s coupon issuance, and NLGR, a neighbor‑list generative reranking system that leverages non‑autoregressive sampling and reward‑based training to boost hit‑ratio performance on public and internal datasets, demonstrating the effectiveness of context‑aware uplift modeling and neighbor‑list reranking for aggregation‑page advertising.
