Machine Learning for Extreme Weather Variability

Project Summary

The project will forecast extreme weather events using multimodal and probabilistic machine learning/deep learning methods to contribute in improvements in flood/drought management. That is to reduce the human and social impacts of flood/drought events caused by weather phenomena such as storms and hurricanes and to support more sustainable development in vulnerable areas. The current numerical weather models face challenges in terms of the complexity of extreme weather systems and the non-linear dynamics of meteorological and topographical predictors. Also, data limitations, such as uncertainties in sensor measurements, and missing data, can distort prediction quality. Additionally, concerns  have been expressed for their interpretability along with the computational cost of deep learning models. This project will address these challenges by developing systems that combine the diversity of data sources and incorporate uncertainty quantification. This allows us to take advantage of the multiple, complementary forms in the data and to account for uncertainty, which will improve the quality of the predictions and enable better risk assessment. Moreover, the exploration of explainable artificial intelligence (XAI) methods will enable public trust by increasing the transparency in the model predictions.
