Predicting ambulance demand accurately at a fine resolution in time and space (e.g., every hour and 1 km2^2) is critical for staff / fleet management and dynamic deployment. There are several challenges: though the dataset is typically large-scale, demand per time period and locality is almost always zero. The demand …

More precisely, riskles…
