WQ-Fusion: Dynamic Gated Attention for Cross-Domain Audio Representation

Mingda Lin, Lei Ding, Xinyue Zhou +6

While pre-trained models excel in specialized tasks, learning universal representations across diverse acoustic domains remains challenging. To address this, we propose WQ-Fusion,…

AURA: Adaptive Uncertainty-aware Refinement for LLM-as-a-Judge Auditing

Zilong Zhang, Yi-Ting Hung, Weiyi He +3

Large language models (LLMs) are increasingly used as judges for open-ended generation, as large-scale human evaluation is often expensive and difficult to scale, yet their prefere…

Quantifying and Auditing LLM Evaluation via Positive--Unlabeled Learning

Zilong Zhang, Yi-Ting Hung, Lei Ding +1

Large Language Models (LLMs) are increasingly used as judges for scalable evaluation, yet such LLM--as--a--Judge systems exhibit systematic biases that are decoupled from semantic…

Enhancing Table Reasoning with Deterministic Table-State Rewards

Tung Sum Thomas Kwok, Xinyu Wang, Hengzhi He +9

Large Language Models (LLMs) struggle with multi-step reasoning over structured tables. The primary reason is the lack of explicit supervision for intermediate reasoning states. Ex…

From Table to Cell: Attention for Better Reasoning with TABALIGN

Tung Sum Thomas Kwok, Zeyong Zhang, Xinyu Wang +6

Multi-step LLM reasoning over structured tables fails because planning and execution share no explicit cell-grounding contract. Existing methods constrain the planner to a left-to-…
