SpecTM: Spectral Targeted Masking for Trustworthy Foundation Models
arXiv CS.AI
•
ArXi:2603.22097v1 Announce Type: new Foundation models are now increasingly being developed for Earth observation (EO), yet they often rely on stochastic masking that do not explicitly enforce physics constraints; a critical trustworthiness limitation, in particular for predictive models that guide public health decisions. In this work, we propose SpecTM (Spectral Targeted Masking), a physics-informed masking design that encourages the reconstruction of targeted bands from cross-spectral context during pre.
