V-STAR: A Value‑Driven Reinforcement Learning Paradigm for Generative Recommendation

The paper identifies a structural mismatch between probability‑driven beam search and reward‑driven RL fine‑tuning in generative recommendation, proposes V-STAR with value‑guided efficient decoding (VED) and sibling‑wise GRPO to align decoding and optimization, and demonstrates superior offline and online performance through extensive experiments and ablations.

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.
