GeoGNN: Time Series Geo-Localization using Two-Tower Graph Neural Networks
Researchers have developed GeoGNN, a novel two-tower graph neural network architecture for time series geolocalization. This method infers the geographic origin of time series data by learning embeddings from both geographic adjacency graphs and the time series themselves. Experiments on electricity consumption datasets show GeoGNN significantly improves geolocalization accuracy by approximately 27% on average. AI
