GRAPHIA: Harnessing Social Graph Data to Enhance LLM-Based Social Simulation

Jiarui Ji, Zehua Zhang, Zhewei Wei +3

Large language models (LLMs) have shown promise in simulating human-like social behaviors. Social graphs provide high-quality supervision signals that encode both local interaction…

BARD: budget-aware reasoning distillation

Lujie Niu, Lei Shen, Yi Jiang +4

While long Chain-of-Thought (CoT) distillation effectively transfers reasoning capability to smaller language models, the reasoning process often remains redundant and computationa…

Reasoning Palette: Modulating Reasoning via Latent Contextualization for Controllable Exploration for (V)LMs

Rujiao Long, Yang Li, Xingyao Zhang +7

Exploration capacity shapes both inference-time performance and reinforcement learning (RL) training for large (vision-) language models, as stochastic sampling often yields redund…

SocialDriveGen: Generating Diverse Traffic Scenarios with Controllable Social Interactions

Jiaguo Tian, Zhengbang Zhu, Shenyu Zhang +6

The generation of realistic and diverse traffic scenarios in simulation is essential for developing and evaluating autonomous driving systems. However, most simulation frameworks r…

RAVR: Reference-Answer-guided Variational Reasoning for Large Language Models

Tianqianjin Lin, Xi Zhao, Xingyao Zhang +5

Reinforcement learning (RL) can refine the reasoning abilities of large language models (LLMs), but critically depends on a key prerequisite: the LLM can already generate high-util…

QAgent: A modular Search Agent with Interactive Query Understanding

Yi Jiang, Lei Shen, Lujie Niu +3

Large language models (LLMs) excel at natural language tasks but are limited by their static parametric knowledge, especially in knowledge-intensive task. Retrieval-augmented gener…
