From Hidden Profiles to Governable Personalization: Recommender Systems in the Age of LLM Agents

Jiahao Liu, Mingzhe Han, Guanming Liu +6

Personalization has traditionally depended on platform-specific user models that are optimized for prediction but remain largely inaccessible to the people they describe. As LLM-ba…

Drift-Aware Continual Tokenization for Generative Recommendation

Yuebo Feng, Jiahao Liu, Mingzhe Han +5

Generative recommendation commonly adopts a two-stage pipeline in which a learnable tokenizer maps items to discrete token sequences (i.e. identifiers) and an autoregressive genera…
