When Compression Helps and When It Hurts: Condition-Aware Analysis of Chain-of-Thought Distillation

Siyang Lyu, Zhijing Sun, Xinghao Chen +3

Chain-of-Thought (CoT) distillation transfers multi-step reasoning from large reasoning models to smaller students, but verbose teacher traces inflate both training and inference c…

What Does LLM Refinement Actually Improve? A Systematic Study on Document-Level Literary Translation

Shaomu Tan, Dawei Zhu, Ke Tran +5

Iterative self-refinement is a simple inference-time strategy for machine translation: an LLM revises its own translation over multiple inference-time passes. Yet document-scale re…

Language models can learn implicit multi-hop reasoning, but only if they have lots of training data

Yuekun Yao, Yupei Du, Dawei Zhu +2

Implicit reasoning is the ability of a language model to solve multi-hop reasoning tasks in a single forward pass, without chain of thought. We investigate this capability using GP…

SonicBench: Dissecting the Physical Perception Bottleneck in Large Audio Language Models

Yirong Sun, Yanjun Chen, Xin Qiu +8

Large Audio Language Models (LALMs) excel at semantic and paralinguistic tasks, yet their ability to perceive the fundamental physical attributes of audio such as pitch, loudness,…

PLD: A Choice-Theoretic List-Wise Knowledge Distillation

Ejafa Bassam, Dawei Zhu, Kaigui Bian

Knowledge distillation is a model compression technique in which a compact "student" network is trained to replicate the predictive behavior of a larger "teacher" network. In logit…

Same evaluation, more tokens: On the effect of input length for machine translation evaluation using Large Language Models

Tobias Domhan, Dawei Zhu

Accurately evaluating machine-translated text remains a long-standing challenge, particularly for long documents. Recent work has shown that large language models (LLMs) can serve…
