Codified Finite-state Machines for Role-playing

Letian Peng, Yupeng Hou, Kun Zhou +1

Modeling latent character states is crucial for consistent and engaging role-playing (RP) with large language models (LLMs). Yet, existing prompting-based approaches mainly capture…

Deriving Character Logic from Storyline as Codified Decision Trees

Letian Peng, Kun Zhou, Longfei Yun +2

Role-playing (RP) agents rely on behavioral profiles to act consistently across diverse narrative contexts, yet existing profiles are largely unstructured, non-executable, and weak…

Codified Foreshadowing-Payoff Text Generation

Longfei Yun, Kun Zhou, Yupeng Hou +2

Foreshadowing and payoff are ubiquitous narrative devices through which authors introduce commitments early in a story and resolve them through concrete, observable outcomes. Howev…

CoFiRec: Coarse-to-Fine Tokenization for Generative Recommendation

Tianxin Wei, Xuying Ning, Xuxing Chen +6

In web environments, user preferences are often refined progressively as users move from browsing broad categories to exploring specific items. However, existing generative recomme…

Mosaic-IT: Cost-Free Compositional Data Synthesis for Instruction Tuning

Ming Li, Pei Chen, Chenguang Wang +5

Finetuning large language models with a variety of instruction-response pairs has enhanced their capability to understand and follow instructions. Current instruction tuning primar…

RuleAgent: Discovering Rules for Recommendation Denoising with Autonomous Language Agents

Zongwei Wang, Min Gao, Junliang Yu +3

The implicit feedback (e.g., clicks) in real-world recommender systems is often prone to severe noise caused by unintentional interactions, such as misclicks or curiosity-driven be…
