Quentin Paletta

I am a research fellow at the European Space Research Institute of the European Space Agency (ESA) in Frascati in collaboration with the ESA Climate Office in Harwell, where I work on computer vision and machine learning for solar energy forecasting. 🌤️

Previously at the University of Cambridge, I have developped deep learning algorithms for advancing solar nowcasting based on cloud cover observations from sky cameras and weather satellites.

I'm interested in computer vision, machine learning, earth observations and solar energy. Much of my research is about improving solar forecasting tools from cloud cover observations. Representative papers are highlighted.

blind-date Improving cross-site generalisability of vision-based solar forecasting models with physics-informed transfer learning
Quentin Paletta, Yuhao Nie, Yves-Marie Saint-Drenan, Bertrand Le Saux,
Energy Conversion and Management, 2024

Forecasting solar energy accurately is good, generalising beyond the location where the model was trained is even better! Here, we explore diverse zero-shot and few-shot learning tasks based on a model pre-trained at another location.

blind-date SkyGPT: Probabilistic Ultra-short-term Solar Forecasting Using Synthetic Sky Images from Physics-constrained VideoGPT
