Meituan's Exploration and Practice in Advertising Algorithm: Information Flow Ad Estimation

Meituan’s advertising algorithm research, presented at Tech Salon #81, outlines the evolution of its information‑flow ad CTR estimation from tree models to sparse large‑scale DNNs, describes three current modeling directions—user‑side timelines and spatial lines, link‑side page/card reconstruction, and LLM‑based knowledge injection—and details practical implementations such as decision‑path modules, ultra‑long/ultra‑wide sequence handling, full‑reconstruction of pages and cards with a Context Modeling Transformer, concluding that combining algorithmic innovation with engineering effort is essential while large‑model integration remains a long‑term challenge.
