PatternFormer: Learning Multiple Solution Patterns in Reaction--Diffusion Systems

Zhipeng Chang, Wenpeng Yin, Wenrui Hao

Many nonlinear models across physics, chemistry, and biology exhibit multiple solutions for the same parameters, and capturing this entire solution set is essential for understandi…

CleanCodec: Efficient and Robust Speech Tokenization via Perceptually Guided Encoding

Eugene Kwek, Feng Liu, Rui Zhang +1

Neural audio codecs are a key component of speech processing pipelines, compressing audio into discrete tokens for downstream modeling. However, existing codecs struggle to balance…

Bridging the Know-Act Gap via Task-Level Autoregressive Reasoning

Jihyun Janice Ahn, Ryo Kamoi, Berk Atil +34

LLMs often generate seemingly valid answers to flawed or ill-posed inputs. This is not due to missing knowledge: under discriminative prompting, the same models can mostly identify…

Functionality-Oriented LLM Merging on the Fisher--Rao Manifold

Jiayu Wang, Zuojun Ye, Wenpeng Yin

Weight-space merging aims to combine multiple fine-tuned LLMs into a single model without retraining, yet most existing approaches remain fundamentally parameter-space heuristics.…

Prompt-Reverse Inconsistency: LLM Self-Inconsistency Beyond Generative Randomness and Prompt Paraphrasing

Jihyun Janice Ahn, Wenpeng Yin

While the inconsistency of LLMs is not a novel topic, prior research has predominantly addressed two types of generative inconsistencies: i) Randomness Inconsistency: running the s…

Accelerating Causal Network Discovery of Alzheimer Disease Biomarkers via Scientific Literature-based Retrieval Augmented Generation

Xiaofan Zhou, Liangjie Huang, Pinyang Cheng +4

The causal relationships between biomarkers are essential for disease diagnosis and medical treatment planning. One notable application is Alzheimer's disease (AD) diagnosis, where…
