Balancing Semantics and Efficiency: A Large‑Scale Personalized Generative Retrieval Method (ICDM 2025)

The paper proposes Hi‑Gen, a generative retrieval framework for large‑scale e‑commerce that jointly models semantic relevance and efficiency through discriminative product vectors, category‑guided hierarchical clustering, and a position‑aware loss, achieving more accurate and faster personalized recall.

Breaking Homogenization: Redesigning Multi‑Scenario Recommendation by Uncovering Knowledge‑Sharing Traps

The paper reveals that knowledge‑sharing across recommendation domains causes homogenized results that boost per‑scene accuracy yet shrink overall GMV, and proposes the DPOMR algorithm with manual rules and an industrial‑grade reference model to restore domain diversity and improve platform‑wide order volume.

MMQ Advances Multimodal Fusion and Aligns Behavior for Large-Scale Recommendation Models

The paper introduces MMQ, a multimodal mixture‑of‑quantization semantic‑ID framework that compresses item multimodal features via shared‑specific expert networks and behavior‑aware fine‑tuning, achieving lower reconstruction loss, superior recall and ranking performance, and online gains of +1.29% REV, +4.33% CVR, +2.61% GMV, and +1.18% ROI.

Can Recommendation Ranking Models Follow the LLM Scaling Law? Introducing GPSD for Scalable Transformers

The paper analyzes why enlarging discriminative recommendation models leads to severe over‑fitting, proposes a two‑stage Generative Pretraining for Scalable Discriminative Recommendation (GPSD) that freezes sparse embeddings, and demonstrates across massive e‑commerce data, public benchmarks, and production A/B tests that the approach restores the classic scaling‑law behavior where larger models consistently improve performance.

How Large‑Model AI Transforms Multilingual E‑Commerce Search

Leveraging multilingual large‑language models such as Qwen, the authors reconstruct query understanding, product understanding, and relevance ranking for Alibaba’s international e‑commerce platforms, build the ME‑LLM base model with domain‑specific pre‑training, and demonstrate significant gains in semantic relevance, query rewriting, and downstream metrics like GMV.
