  • Publication number: 20200334554
    Abstract: A server includes memory and a processor that obtains a log created by a first node monitored on a V2X network, selects predetermined information therefrom, and performs supervised machine learning using the selected predetermined information as training data to create a model for a monitoring node that monitors the first node. The log associatively includes a time, and at the time: first node status information as indicated by at least one of sensor or control data on the first node; first anomaly information indicating whether an anomaly occurred on the first node; and second anomaly information indicating whether an anomaly occurred on a second, surrounding node of the first node that communicates with the first node. When the first anomaly information indicates an anomaly, or when the first and second anomaly information indicate no anomaly and an anomaly, respectively, the associated status information is selected as the predetermined information.
