When it comes to predicting when and where crimes will occur, a growing number of communities in Japan are turning to artificial intelligence. Some municipalities have already started to fine tune citizen patrol routes based on data gathered by AI in a bid to prevent crime, while other communities are considering similar steps. Nagoya began to use such a system last July, after a successful test resulted in the detection of crimes. The system currently in use was developed by Tokyo-based Singular Perturbations Inc., a company founded by experts in mathematics and statistics. It allows citizens on patrol to download an app with recommended patrol routes, which are generated following an AI analysis.
