Abstract
The object is to output the youthfulness degree of a user. A youthfulness degree output device 1 includes: a storage unit 10 that stores a scoring model for predicting the youthfulness degree of a user by inputting the user's age and a log frequency related to logs associated with the user's behavior obtained by a mobile terminal 2 carried by the user; an acquisition unit 11 that acquires a target user's age and the log frequency; and an output unit 13 that outputs the youthfulness degree of the target user predicted by inputting the target user's age and the log frequency acquired by the acquisition unit 11 to the scoring model stored in the storage unit 10.
Claims10
A youthfulness degree output device, comprising processing circuitry configured to:
- store a prediction model for predicting a youthfulness degree of a user by inputting the user's age and a log frequency related to logs associated with the user's behavior obtained by a terminal carried by the user;
- acquire a target user's age and the log frequency;
- and
- output a youthfulness degree of the target user predicted by inputting the acquired target user's age and the acquired log frequency to the stored prediction model,
- wherein the prediction model predicts a youthfulness degree based on a cumulative distribution function for each age calculated by counting the log frequency for each of a plurality of users by age.
A youthfulness degree output method executed by a youthfulness degree output device which stores a prediction model for predicting a youthfulness degree of a user by inputting the user's age and a log frequency related to logs associated with the user's behavior obtained by a terminal carried by the user, the youthfulness degree output method comprising:
- an acquisition step for acquiring a target user's age and the log frequency;
- and
- an output step for outputting a youthfulness degree of the target user predicted by inputting the target user's age and the log frequency acquired in the acquisition step to the stored prediction model,
- wherein the prediction model predicts a youthfulness degree based on a cumulative distribution function for each age calculated by counting the log frequency for each of a plurality of users by age.
