LatentRefusal: Latent-Signal Refusal for Unanswerable Text-to-SQL Queries

Xuancheng Ren, Shijing Hu, Zhihui Lu +2

In LLM-based text-to-SQL systems, unanswerable and underspecified user queries may generate not only incorrect text but also executable programs that yield misleading results or vi…

Prefix Probing: Lightweight Harmful Content Detection for Large Language Models

Jirui Yang, Hengqi Guo, Zhihui Lu +6

Large language models often face a three-way trade-off among detection accuracy, inference latency, and deployment cost when used in real-world safety-sensitive applications. This…

Bridging Draft Policy Misalignment: Group Tree Optimization for Speculative Decoding

Shijing Hu, Jingyang Li, Zhihui Lu +1

Speculative decoding accelerates large language model (LLM) inference by letting a lightweight draft model propose multiple tokens that the target model verifies in parallel. Yet e…

GRIFFIN: Effective Token Alignment for Faster Speculative Decoding

Shijing Hu, Jingyang Li, Xingyu Xie +3

Speculative decoding accelerates inference in large language models (LLMs) by generating multiple draft tokens simultaneously. However, existing methods often struggle with token m…
