Why Specialist Models Still Matter: A Heterogeneous Multi-Agent Paradigm for Medical Artificial Intelligence

Yanan Wang, Shuaicong Hu, Jian Liu, Guohui Zhou, Aiguo Wang, Cuiwei Yang

ICML 2026poster

The impressive performance of generalist large language models (LLMs) such as GPT-4 and Claude in healthcare raises a critical question: will domain-specific medical specialist models become obsolete? We argue that the future of medical artificial intelligence (AI) lies not in building monolithic me…

A Fast Sparse Covariance-Based Fitting Method for DOA Estimation via Non-Negative Least Squares

Chundi Zheng, Huihui Chen, Aiguo Wang

ICASSP 2020accepted

A fast sparse covariance-based fitting algorithm with the non-negative least squares (NNLS) form is proposed for the direction of arrival (DOA) estimation. The Khatri-Rao product of the array manifold of the uniform linear arrays is utilized to achieve the dimension reducing transformation after vec…
