A new paper proposes a "prior-matched evaluation" method for Earth-observation classifiers, specifically demonstrated on Sentinel-1's internal-wave detection. The method addresses the discrepancy between balanced-test scores and real-world operational performance, which can be significantly lower due to imbalanced data priors. By introducing three reporting figures—balanced-test, operational-prior, and real post-deployment—the approach offers a more honest measure of a classifier's effectiveness. This technique aims to improve the development cycle for rare-event detectors in operational Earth-observation services. AI
