Learning Cascade Ranking as One Network

no code implementations12 Mar 2025 Yunli Wang, Zhen Zhang, Zhiqiang Wang, Zixuan Yang, Yu Li, Jian Yang, Shiyang Wen, Peng Jiang, Kun Gai

Recent advances such as RankFlow and FS-LTR have introduced interaction-aware training paradigms but still struggle to 1) align training objectives with the goal of the entire cascade ranking (i. e., end-to-end recall) and 2) learn effective collaboration patterns for different stages.

Adaptive$^2$: Adaptive Domain Mining for Fine-grained Domain Adaptation Modeling

no code implementations11 Dec 2024 Wenxuan Sun, Zixuan Yang, Yunli Wang, Zhen Zhang, Zhiqiang Wang, Yu Li, Jian Yang, Yiming Yang, Shiyang Wen, Peng Jiang, Kun Gai

To the best of our knowledge, Adaptive$^2$ is the first approach to automatically learn both domain identification and adaptation in online advertising, opening new research directions for this area.
