Exploring DINO: Emergent Properties and Limitations for Synthetic Aperture Radar Imagery

no code implementations5 Oct 2023 Joseph A. Gallego-Mejia, Anna Jungbluth, Laura Martínez-Ferrer, Matt Allen, Francisco Dorr, Freddie Kalaitzis, Raúl Ramos-Pollán

We observe a small improvement in model performance with pre-training compared to training from scratch and discuss the limitations and opportunities of SSL for remote sensing and land cover segmentation.

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

no code implementations3 Oct 2023 Laura Martínez-Ferrer, Anna Jungbluth, Joseph A. Gallego-Mejia, Matt Allen, Francisco Dorr, Freddie Kalaitzis, Raúl Ramos-Pollán

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).

Fewshot learning on global multimodal embeddings for earth observation tasks

no code implementations29 Sep 2023 Matt Allen, Francisco Dorr, Joseph A. Gallego-Mejia, Laura Martínez-Ferrer, Anna Jungbluth, Freddie Kalaitzis, Raúl Ramos-Pollán

In this work we pretrain a CLIP/ViT based model using three different modalities of satellite imagery across five AOIs covering over ~10\% of Earth's total landmass, namely Sentinel 2 RGB optical imagery, Sentinel 1 SAR radar amplitude and interferometric coherence.

On-orbit model training for satellite imagery with label proportions

1 code implementation21 Jun 2023 Raúl Ramos-Pollán, Fabio A. González

This work addresses the challenge of training supervised machine or deep learning models on orbiting platforms where we are generally constrained by limited on-board hardware capabilities and restricted uplink bandwidths to upload.

Kernel Density Matrices for Probabilistic Deep Learning

2 code implementations26 May 2023 Fabio A. González, Raúl Ramos-Pollán, Joseph A. Gallego-Mejia

In doing so, we provide a versatile representation of marginal and joint probability distributions that allows us to develop a differentiable, compositional, and reversible inference procedure that covers a wide range of machine learning tasks, including density estimation, discriminative learning, and generative modeling.
