Learning device, learning method, and learning program

Abstract

To make use of a vast amount of data accumulated in relation to use of services.SOLUTION: An information processing device according to the present invention includes an acquisition unit and a learning unit. Upon receiving user conditions related to a user as a target of learning, the acquisition unit acquires feature values indicating features of users who satisfy the conditions from a database storing feature amounts indicating features of users, and acquires action information indicating actions took by the users who satisfy the user conditions from a database storing action information indicating actions took by users. The learning unit makes a model learn a relation between the feature values and the action information acquired by the acquisition unit.SELECTED DRAWING: Figure 6

Claims

1. Upon receiving user conditions regarding the user to be trained, the acquisition unit retrieves feature quantities representing the characteristics of a user who satisfies the user conditions from a database in which feature quantities representing the characteristics of each user are registered, and retrieves action information representing the actions taken by a user who satisfies the user conditions from a database in which action information representing the actions taken by each user is registered. A learning unit that trains a model on the relationship between the feature quantities acquired by the acquisition unit and the behavioral information. A learning device characterized by having the following features.

2. The acquisition unit is, When a user submits a query specifying the user's behavior to be learned, the system obtains the behavior information corresponding to the behavior specified by the query, and then obtains the feature quantities associated with the obtained behavior information. The learning device according to feature 1.

3. The acquisition unit is, When the system receives a user's specification of the user's characteristics to be learned, it obtains the feature quantities corresponding to the specified characteristics and retrieves the behavioral information associated with the obtained feature quantities. The learning device according to feature 1.

4. A learning method performed by a computer, Upon receiving user conditions regarding the user to be trained, the acquisition process includes obtaining feature quantities representing the characteristics of a user who satisfies the user conditions from a database in which feature quantities representing the characteristics of each user are registered, and obtaining action information representing the actions taken by a user who satisfies the user conditions from a database in which action information representing the actions taken by each user is registered. A learning process in which the relationship between the feature quantities obtained in the acquisition process and the behavioral information is learned in a model. A learning method characterized by including the following.

5. On the computer, The acquisition procedure involves receiving user conditions regarding the users to be trained, obtaining feature quantities representing the characteristics of users who satisfy the user conditions from a database containing feature quantities representing the characteristics of each user, and obtaining action information representing the actions taken by users who satisfy the user conditions from a database containing action information representing the actions taken by each user. A learning procedure to train a model on the relationship between the features obtained by the acquisition procedure and the behavioral information, and A learning program characterized by causing the execution of [a specific action].
