VITA is a variational pretraining framework that learns weather representations from rich satellite data and transfers them to yield prediction tasks with limited ground-based measurements. ## Overview VITA addresses the data asymmetry problem in agricultural AI: pretraining uses 31 meteorological variables from NASA POWER satellite data, while deployment relies on only 6 basic weather features. Through variational pretraining with a seasonality-aware sinusoidal prior, VITA achieves state-of-the-art performance in predicting corn and soybean yields across 763 U.S. Corn Belt counties, particularly during extreme weather years. ## Citation ```bibtex @inproceedings{hasan2026vita, title={VITA: Variational Pretraining of Transformers for Climate-Robust Crop Yield Forecasting}, author={Adib Hasan and Mardavij Roozbehani and Munther Dahleh}, booktitle={Proceedings of the 40th AAAI Conference on Artificial Intelligence}, year={2026}, url={https://arxiv.org/abs/2508.03589}, } ```
