Abstract: A generation device includes: an acquisition unit that acquires one or more pieces of identification information imparted to a component in a certain hierarchy among a plurality of components, the one or more pieces of identification information being identification information identifiably imparted with the type and the number of components in a lower hierarchy; a generation unit that generates a trained model corresponding to each piece of identification information for estimating a state of a battery by learning operating data for each of the one or more pieces of identification information; and an output unit that outputs the generated trained model.

Abstract: A server includes: an acquisition part that acquires and stores article data in a memory; a determination part that calculates an accuracy of a machine learning model which performs machine learning by using the article data stored in the memory, and determines at least one of reduction in data item and reduction in sampling rate so that the calculated accuracy satisfies a reference accuracy; and a transmission part that transmits, to an article, control data for controlling the article to send the article data by using at least one of a data item after the reduction and a sampling rate after the reduction.

Abstract: To detect connection between a secondary battery and a charger, determine whether or not a state of the secondary battery is stabilized in a case of detecting the connection, measure a first open circuit voltage that is an open circuit voltage before charging of the secondary battery in a case of determining that a state of the secondary battery is stabilized, instruct the charger to start charging of the secondary battery, detect end of charging of the secondary battery, determine whether or not a state of the secondary battery is stabilized in a case of detecting end of charging of the secondary battery, measure a second open circuit voltage that is an open circuit voltage after charging of the secondary battery in a case of determining that a state of the secondary battery is stabilized, and notify the user of end of charging of the secondary battery.

Abstract: A dashboard camera acquires video data from a camera that captures the surroundings of a vehicle, acquires sensor data including at least one of acceleration, speed, and angular velocity of the vehicle, gives time information indicating time of acquisition to each of the video data and the sensor data, and transmits the sensor data to a data analysis server when an event occurs in the vehicle, the data analysis server identifies the content of the event occurred in the vehicle based on the sensor data and transmits an identification result to the dashboard camera, and when the identified event is determined to be the predetermined event, the dashboard camera specifies video data to which time information same as the time information given to the sensor data used for the identification is given, and transmits the specified video data to a video accumulation server.

Abstract: In an information collection method of the present disclosure, a processor of an information collection system acquires event sensor data and identification information from an on-vehicle terminal or a passenger terminal, the event sensor data being output, in response to an event trigger, from an on-vehicle sensor mounted on the on-vehicle terminal or a passenger sensor mounted on the passenger terminal, the identification information identifying an output source of the event sensor data, identifies the passenger terminal associated with the identification information when the identification information indicates the on-vehicle terminal, identifies the on-vehicle terminal associated with the identification information when the identification information indicates the passenger terminal, requests sensor data from the identified passenger terminal or on-vehicle terminal, acquires the sensor data from a request destination, and stores the event sensor data and the sensor data in association with each other in a

Abstract: A contribution level determination method includes: obtaining, from a first storage device, records of annotation works for each of one or more units of target data for which the annotation works carried out by each of workers that use crowdsourcing have been completed; and calculating work contribution levels for each of worker IDs representing a different one of the workers, in accordance with a predetermined weighting rule stored in a second storage device, by referring to the records. In the calculating of the contribution levels, for each of the one or more units of target data, the work contribution level is calculated using a heavier weight for the worker ID representing a particular worker who carried out the annotation work initially than for the work contribution levels for the worker IDs representing the workers who carried out annotation works after the particular worker, in the order of the annotation works.
