How Much of a Model Do We Need? Redundancy and Slimmability in Remote Sensing Foundation Models
Researchers have investigated the redundancy and efficiency of foundation models used in remote sensing (RS). Their findings suggest that RS models are overparameterized and encode information redundantly, retaining significant accuracy even after aggressive width reduction. This contrasts with models pretrained on natural images, which degrade more sharply under similar reductions. The study proposes post-hoc slimming as a practical deployment strategy for resource-constrained RS applications and as a diagnostic tool for understanding model redundancy. AI
