SFAD: Speculative Factuality-Aware Decoding

Guanqiao Chen, Di Wang, Lijie Hu

As one of the most critical challenges in large language models, contextual faithfulness directly determines their reliability in knowledge-intensive applications. This task is par…

Predicting LLM Output Length via Entropy-Guided Representations

Huanyi Xie, Yubin Chen, Liangyu Wang +2

The long-tailed distribution of sequence lengths in LLM serving and reinforcement learning (RL) sampling causes significant computational waste due to excessive padding in batched…

Concept-Based Dictionary Learning for Inference-Time Safety in Vision Language Action Models

Siqi Wen, Shu Yang, Shaopeng Fu +3

Vision Language Action (VLA) models close the perception action loop by translating multimodal instructions into executable behaviors, but this very capability magnifies safety ris…

Global Evolutionary Steering: Refining Activation Steering Control via Cross-Layer Consistency

Xinyan Jiang, Wenjing Yu, Di Wang +1

Activation engineering enables precise control over Large Language Models (LLMs) without the computational cost of fine-tuning. However, existing methods deriving vectors from stat…

Understanding the Dynamics of Demonstration Conflict in In-Context Learning

Difan Jiao, Di Wang, Lijie Hu

In-context learning enables large language models to perform novel tasks through few-shot demonstrations. However, demonstrations per se can naturally contain noise and conflicting…
