The U.S. Department of Homeland Security (DHS) has kicked off a challenge to improve the algorithm Transportation Security Administration (TSA) uses to detect airport security threats. The goal of this competition is to reduce the number of false alarms while maintaining high levels of security using image data. This is because when the scanning equipment predicts a potential threat, a TSA agent must engage in a secondary, manual screening process that slows everything down. By reducing false alarms, the passenger experience can be greatly improved. The challenge offers $1.5 million in prize money and is hosted by Kaggle.
