Abstract: An accident risk diagnosis apparatus stores travel data that is data indicating a travel state of each of a plurality of vehicles for each date and time and information on past accidents of the plurality of vehicles, extracts the travel data for a predetermined period before an accident day and the travel data on the accident day from among the travel data, generates training data for each trip that is a period from activation to termination of a vehicle based on an extracted travel data, generates an accident risk diagnosis model that is a machine learning model for diagnosing an accident risk using the training data, inputs a feature in a trip of a vehicle to be diagnosed to the accident risk diagnosis model to diagnose the accident risk, and transmits a diagnosis result to an in-vehicle device mounted on the vehicle.

Abstract: An object of the invention is to harmonize prediction accuracy and an analysis time of an ensemble model. Therefore, when performing data analysis using an ensemble model 300 that makes an inference by integrating inferences by first to n-th models, an i-th model (1?i?n) constituting the ensemble model 300 is selected from an i-th model group of the model data, at least one model group of the first to n-th model groups includes a plurality of models, and the first to n-th models capable of constituting an ensemble model satisfying a performance requirement for data analysis and a constraint requirement for time required for the data analysis are selected from the first to n-th model groups 301 to 303.

Abstract: To provide a walking mode display method, a walking mode display system and a walking mode analyzer each of which allows for analysis of a walking mode of a user and display thereof in an easily understandable manner. The walking mode display method includes: selecting measurement of a walker and measurement of a reference walker to be compared with the walker; displaying a first walking model that displays a walking for one walking step of the walker as an animation; displaying a second walking model that displays a walking for one walking step of the reference walker as the animation; and displaying a magnitude of predetermined feature amount data related to the measurement of the walker and the magnitude of predetermined feature amount data related to the measurement of the reference walker in a comparable manner.

Abstract: It is an object to simply control an internal temperature of each individual container. A container comprises a cover portion; a box body including; a containing space formed therein; and an opening surface openable and closable by the cover portion; and a recording device including: a storage unit storing measurement information containing an internal temperature of the containing space and time when measuring the temperature; and a communication unit transmitting the measurement information to an external device, the recording device being provided in the cover portion, or the box body, or within the containing space, outside surfaces of the cover portion and the box body being covered with a metallic material to block communications between the communication unit and the external device, the metallic material used blocking of the communications between the communication unit and the external device being cancelled upon opening the cover portion.
