Rapid Adaptation of Earth Observation Foundation Models for Segmentation

Karthick Panner Selvam, Raul Ramos-Pollan, Freddie Kalaitzis

This study investigates the efficacy of Low-Rank Adaptation (LoRA) in fine-tuning Earth Observation (EO) foundation models for flood segmentation. We hypothesize that LoRA, a param…

Uncertainty and Generalizability in Foundation Models for Earth Observation

Raul Ramos-Pollan, Freddie Kalaitzis, Karthick Panner Selvam

We take the perspective in which we want to design a downstream task (such as estimating vegetation coverage) on a certain area of interest (AOI) with a limited labeling budget. By…

Exploring Generalisability of Self-Distillation with No Labels for SAR-Based Vegetation Prediction

Laura Martínez-Ferrer, Anna Jungbluth, Joseph A. Gallego-Mejia +4

In this work we pre-train a DINO-ViT based model using two Synthetic Aperture Radar datasets (S1GRD or GSSIC) across three regions (China, Conus, Europe). We fine-tune the models o…
