Beyond Co-Localization: DeepCoEx Learns Exclusion-Aware Spatial Representations in Mass Spectrometry Imaging via Dual-Contrastive Learning

Abstract Mass spectrometry imaging (MSI) provides spatially resolved molecular profiles, yet the existing computational workflows are heavily biased toward co-localization and remain limited in characterizing exclusion-like spatial relationships, especially when reliable negative...

Few-shot learning for expert consensus severity stratification in newly diagnosed crohn’s disease

Early and accurate assessment of disease severity is important for standardizing baseline risk stratification and supporting treatment planning in newly diagnosed Crohn’s disease. This study used electronic medical record data, a few-shot learning algorithm, and SHAP-based interp...
