When Is a Conformal Guarantee Fair? Auditing Silent Subgroup Under-Coverage in Alzheimer's Disease Longitudinal Prediction
Lujia Zhong, Xinkai Wang, Shuo Huang +1
Longitudinal prediction of Alzheimer's disease biomarkers increasingly informs clinical decisions, and a forecast is only useful if it also reports how much to trust it. Conformal…
TabPFN beyond Tabular Data: Calibration and Accuracy on Multimodal Embeddings
Jingxiang Zhang, Lujia Zhong, Zijie Zhu +2
The paper evaluates TabPFN as a plug‑and‑play, training‑free classification head for frozen image, text, and audio encoders, showing it improves calibration (lower NLL and ECE) whi…
Dimension expansion for simulation-efficient nanophotonic neural networks
Shuo Huang, Mahsa Torfeh, Lujia Zhong +3
Inverse design of nanophotonic structures is challenging due to the large design space, nonlinear structure-response relationships, and the high computational cost of iterative ele…
A Surface-based Multimodal Framework for Multitask Analysis in Alzheimer's Disease
Shuo Huang, Jianwei Zhang, Lujia Zhong +4
Alzheimer's Disease (AD) is a progressive neurodegenerative disorder, and longitudinal analysis is critical for early detection and effective intervention. Developing models capabl…
PromptDx: Differentiable Prompt Tuning for Multimodal In-Context Alzheimer's Diagnosis
Lujia Zhong, Yihao Xia, Shuo Huang +2
Deep learning models in medical imaging typically operate as parametric memory, diagnosing patients by recalling fixed knowledge learned during training. This contrasts sharply wit…
NeuroAgent: LLM Agents for Multimodal Neuroimaging Analysis and Research
Lujia Zhong, Yihao Xia, Jianwei Zhang +4
Multimodal neuroimaging analysis often involves complex, modality-specific preprocessing workflows that require careful configuration, quality control, and coordination across hete…
