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...
