AI data quality metrics misaligned with human perception and task performance

A new paper published on arXiv explores the disconnect between automated data quality metrics and their actual utility for deep learning models, particularly in Earth observation. The research highlights that common metrics like FID and LPIPS, which focus on visual fidelity, do not always align with human perception or downstream task performance. The study found that perturbations like rotation can significantly alter metric scores without affecting human recognition, and synthetic data that scores poorly on automated metrics can still improve downstream performance when used alongside real data. The authors conclude that evaluating synthetic datasets for geospatial applications should prioritize human evaluation and task-specific performance over purely visual fidelity metrics. AI

IMPACT Highlights potential pitfalls in using automated metrics for synthetic data quality, impacting AI model training and evaluation.
