Meta-learning with METEOR
Meta-learning with METEOR involves optimizing models to be proficient in various tasks simultaneously by training on multiple small datasets. By splitting one large land cover dataset into many small sets of data corresponding to different locations, the model learns to distinguish varied land cover classes efficiently across different geographic regions. This approach enhances the model's understanding of contextual patterns and enables better classification of distinct land cover types such as ice and desert, reflecting a practical and realistic classification framework.
Few-shot Learning for Deforestation Monitoring
METEOR's few-shot learning capabilities demonstrate effectiveness in tasks like deforestation monitoring by requiring minimal training examples for new tasks. With experiments highlighting five examples per class, like deforested and non-deforested areas, the model showcases rapid adaptation and accurate prediction abilities. Leveraging pre-training on global land cover data sets like Sentinel-1 and Sentinel-2MSMS datasets, METEOR enables efficient fine-tuning for specific tasks, minimizing the need for extensive training data collection.
Enhancing Task Adaptability and Future Prospects
The METEOR model's adaptability extends to diverse downstream tasks beyond land cover classification, including change detection in planetary images and urban density classifications. By defining prototypes with few training examples per class, the model can address dynamic scenarios, such as temporal change detection. This innovative approach challenges traditional class definitions and task representations, emphasizing the importance of task-specific meta-learning in earth observation models for enhanced task performance and model generalizability.
In this episode, I caught up with Marc Rußwurm to learn about Meta-learning with Meteor. Our conversation starts with a discussion about meta-learning and the training of Meteor, and how this approach differs from the typical approaches taken to train foundational models. We cover the advantages and challenges of this technique, and discuss the fine-tuning of Meteor with minimal examples—as few as five—for tasks like deforestation monitoring and change detection, and consider what the future could hold for this approach. Meteor showcases the significant potential of few-shot learning for processing remote sensing imagery and proves it's possible to tackle tasks even when very few training examples are available.
Bio: Marc Rußwurm is Assistant Professor of Machine Learning and Remote Sensing at Wageningen University. His background is in Geodesy and Geoinformation, and he obtained a Ph.D. in Remote Sensing Technology at TU Munich. During his Ph.D., he could visit the European Space Agency and the University of Oxford as a participant in the Frontier Development Lab in 2018, the Obelix Laboratory in Vannes, and the Lobell Lab in Stanford. As a postdoctoral researcher, he joined the Environmental Computational Science and Earth Observation Laboratory at EPFL, Switzerland. His research interests are developing modern machine learning methods for real-world remote sensing problems, such as classifying vegetation from satellite time series and detecting marine debris in the oceans. He is interested in domain shifts and transfer learning problems naturally arising from geographic data.
