Learning Robust Personalized Prompts for LLM-Driven Sequential Recommendation

Xiaolin Zheng, Qiyong Zhong, Jiajie Su +1

LLM-driven sequential recommendation formulates next-item prediction as autoregressive generation conditioned on natural-language prompts. However, minor wording changes in semanti…

MAS-OPD: On-Policy Distillation for Multi-agent Systems

Qiyong Zhong, Mao Zheng, Mingyang Song +5

Multi-agent systems (MAS) split a task across specialized roles and are promising on complex tasks, yet a prevailing approach relies on inference-time orchestration alone. General-…

USA: Update-aware SAM for Cross-domain On-Policy Disitllation of Language Agents

Qiyong Zhong, Mao Zheng, Mingyang Song +6

On-policy distillation instils multi-turn agentic reasoning through dense token-level supervision on the student's own trajectories, but a single domain saturates early, so further…

Pctx: Tokenizing Personalized Context for Generative Recommendation

Qiyong Zhong, Jiajie Su, Yunshan Ma +2

Generative recommendation (GR) models tokenize each action into a few discrete tokens (called semantic IDs) and autoregressively generate the next tokens as predictions, showing ad…
