MANIFOLDFORMER: GEOMETRIC DEEP LEARNING FOR NEURAL DYNAMICS ON RIEMANNIAN MANIFOLDS

ICASSP 2026poster

Existing EEG foundation models mainly treat neural signals as generic time series in Euclidean space, ignoring the intrinsic geometric structure of neural dynamics that constrains brain activity to low-dimensional manifolds. This fundamental mismatch between model assumptions and neural geometry lim…

GraphCheck: Breaking Long-Term Text Barriers with Extracted Knowledge Graph-Powered Fact-Checking

ACL 2025long

Large language models (LLMs) are widely used, but they often generate subtle factual errors, especially in long-form text. These errors are fatal in some specialized domains such as medicine. Existing fact-checking with grounding documents methods face two main challenges: (1) they struggle to under…

LMOD: A Large Multimodal Ophthalmology Dataset and Benchmark for Large Vision-Language Models

NAACL 2025findings

The prevalence of vision-threatening eye diseases is a significant global burden, with many cases remaining undiagnosed or diagnosed too late for effective treatment. Large vision-language models (LVLMs) have the potential to assist in understanding anatomical information, diagnosing eye diseases, a…

MMLU-ProX: A Multilingual Benchmark for Advanced Large Language Model Evaluation

EMNLP 2025

Existing large language model (LLM) evaluation benchmarks primarily focus on English, while current multilingual tasks lack parallel questions that specifically assess cross-lingual reasoning abilities. This dual limitation makes it challenging to assess LLMs’ performance in the multilingual setting

Med-PRM: Medical Reasoning Models with Stepwise, Guideline-verified Process Rewards

EMNLP 2025

Large language models have shown promise in clinical decision making, but current approaches struggle to localize and correct errors at specific steps of the reasoning process. This limitation is critical in medicine, where identifying and addressing reasoning errors is essential for accurate diagno

MedCalc-Bench: Evaluating Large Language Models for Medical Calculations

NeurIPS 2024oral

Current benchmarks for evaluating large language models (LLMs) in medicine are primarily focused on question-answering involving domain knowledge and descriptive reasoning. While such qualitative capabilities are vital to medical diagnosis, in real-world scenarios, doctors frequently use clinical ca…

MedINST: Meta Dataset of Biomedical Instructions

EMNLP 2024finding

The integration of large language model (LLM) techniques in the field of medical analysis has brought about significant advancements, yet the scarcity of large, diverse, and well-annotated datasets remains a major challenge. Medical data and tasks, which vary in format, size, and other parameters, r…
