[NOVA Math] Statistics and Risk Management Seminar

The Center of Mathematics and Applications (NOVA Math), promote the Seminar of Statistics and Risk Management with the title: “Everything is Connected: Space, Time, EVT, and Graph Neural Networks ". Tanujit Chakraborty (Sorbonne University and Sorbonne Centre for Artificial Intelligence, Abu Dhabi and Paris) is the speaker.

Abstract: Air quality forecasting is a vital space-time challenge with profound implications for public health and environmental management. In this talk, I will introduce E-STGCN (Extreme Spatiotemporal Graph Convolutional Networks), a novel approach that integrates graph convolutional networks with extreme value theory to predict air quality at unprecedented accuracy levels. We will delve into the mathematical underpinnings of E-STGCN, including its ability to capture complex spatiotemporal dependencies across dynamic networks. Emphasis will be placed on how the model processes extreme events, handles multi-scale relationships, and achieves state-of-the-art results on Delhi's air quality data.
