AI software scans satellite images and predicts how many residents are overweight

Scientists have created an AI that can detect obesity from space. The software scans satellite images and predicts how many residents are overweight based on the availability of parks, fast food stores and other buildings in the area. Researchers used deep learning to scan 150,000 high-resolution satellite images from Google Maps in order to identify patterns. They looked at data in six US cities - Bellevue, Seattle, Tacoma, Los Angeles, Memphis, and San Antonio. The team found that features of the built environment explained 64.8 per cent of the variation in obesity between cities.
