- Title: Exploring Generalisability of Self-Distillation with No Labels for
SAR-Based Vegetation Prediction
- Abstract summary: 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 on smaller labeled datasets to predict vegetation percentage, and empirically study the connection between the embedding space of the models and their ability to generalize across diverse geographic regions and to unseen data.

- Abstract: 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 on smaller labeled datasets to predict vegetation
percentage, and empirically study the connection between the embedding space of
the models and their ability to generalize across diverse geographic regions
and to unseen data. For S1GRD, embedding spaces of different regions are
clearly separated, while GSSIC's overlaps. Positional patterns remain during
fine-tuning, and greater distances in embeddings often result in higher errors
for unfamiliar regions. With this, our work increases our understanding of
generalizability for self-supervised models applied to remote sensing.

Open data is frequently released spatially aggregated, usually to comply with privacy policies. But coarse, heterogeneous aggregations complicate coherent learning and integration for downstream AI/ML systems.
We propose an overarching model named Structurally-Aware Recurrent Network (SARN), which integrates structurally-aware spatial attention layers into the Gated Recurrent Unit (GRU) model.
For scenarios with limited historical training data, we show that a model pre-trained on one city variable can be fine-tuned for another city variable using only a few hundred samples.
