Mistletoe: Stealthy Acceleration-Collapse Attacks on Speculative Decoding

Shuoyang Sun, Chang Dai, Hao Fang +6

Speculative decoding has become a widely adopted technique for accelerating large language model (LLM) inference by drafting multiple candidate tokens and verifying them with a tar…

Structural Reward Model: Enhancing Interpretability, Efficiency, and Scalability in Reward Modeling

Xiaoyu Liu, Di Liang, Chang Dai +9

Reward Models (RMs) are key components for evaluating and guiding language model outputs. However, traditional scalar RMs often struggle with incorporating contextual and backgroun…

R-Capsule: Compressing High-Level Plans for Efficient Large Language Model Reasoning

Hongyu Shan, Mingyang Song, Chang Dai +2

Chain-of-Thought (CoT) prompting helps Large Language Models (LLMs) tackle complex reasoning by eliciting explicit step-by-step rationales. However, CoT's verbosity increases laten…

HoPE: Hyperbolic Rotary Positional Encoding for Stable Long-Range Dependency Modeling in Large Language Models

Chang Dai, Hongyu Shan, Mingyang Song +1

Positional encoding mechanisms enable Transformers to model sequential structure and long-range dependencies in text. While absolute positional encodings struggle with extrapolatio…

MTLM: Incorporating Bidirectional Text Information to Enhance Language Model Training in Speech Recognition Systems

Qingliang Meng, Pengju Ren, Tian Li +2

Automatic speech recognition (ASR) systems normally consist of an acoustic model (AM) and a language model (LM). The acoustic model estimates the probability distribution of text g…
