Control method in which, when an updated album creation parameter satisfies a predetermined condition, the updated album creation parameter becomes downloadable to a terminal device of a first user

1. A control method that performs a learning loop, the method comprising:

acquiring first layout data generated based on a first album creation parameter from a server to which layout data generated by a user is uploaded;

outputting an estimated feature value based on the first layout data;

generating a second album creation parameter based on the output estimated feature value;

generating third layout data based on the generated second album creation parameter and an image used for second layout data acquired from the server; and

updating the first album creation parameter and the third album creation parameter based on a feature value based on the generated third layout data and a feature value based on the second layout data,

wherein, in a case when the updated album creation parameter satisfies a predetermined condition, the updated album creation parameter becomes downloadable to a terminal device of a first user, and,

in a case when a number of pieces of layout data uploaded to the server is more than a predetermined number, in the learning loop, only layout data generated by the first user is used, and in a case when the number of pieces of layout data uploaded to the server is less than or equal to the predetermined number, in the learning loop, at least layout data generated by a second user different from the first user is used.

2. The control method according to claim 1 , wherein, by a first feature value based on the first layout data being input to a learning unit as input data, the estimated feature value is output from the learning unit.

3. The control method according to claim 2 , wherein, based on comparison results between a feature value based on the generated third layout data and a feature value based on the second layout data, the parameter of the learning unit is updated.

4. The control method according to claim 1 , wherein, by images used for the second layout data being arranged in a template based on the generated second album creation parameter, the third layout data is generated.

5. The control method according to claim 1 , wherein, in a case when group identification information on the first user and group identification information on the second user are the same, in the learning loop, it is possible to use layout data generated by the second user different from the first user.

6. The control method according to claim 1 , wherein, in a case when the number of pieces of layout data uploaded to the server is less than or equal to the predetermined number, in the learning loop, the layout data generated by the first user and the layout data generated by the second user are used.

7. The control method according to claim 1 , wherein the third album creation parameter is downloaded to a terminal device of the first user by updating of an album creation application.

8. The control method according to claim 7 , wherein the downloaded third album creation parameter is used in a case when new layout data is generated by the album creation application.

9. A control apparatus comprising:

an acquiring unit configured to acquire first layout data generated based on a first album creation parameter from a server to which layout data generated by a user is uploaded;

an outputting unit configured to output an estimated feature value based on the first layout data;

a first generating unit configured to generate a second album creation parameter based on the output estimated feature value;

a second generating unit configured to generate third layout data based on the generated second album creation parameter and an image used for second layout data acquired from the server; and

an updating unit configured to update the first album creation parameter and the third album creation parameter based on a feature value based on the generated third layout data and a feature value based on the second layout data,

wherein, the acquiring unit, the outputting unit, the first generating unit, the second generating unit, and the updating unit perform a learning loop, such that,

in a case when the updated album creation parameter satisfies a predetermined condition, the updated album creation parameter becomes downloadable to a terminal device of a first user,

in a case when a number of pieces of layout data uploaded to the server is more than a predetermined number, in the learning loop, only layout data generated by the first user is used, and,

in a case when the number of pieces of layout data uploaded to the server is less than or equal to the predetermined number, in the learning loop, at least layout data generated by a second user different from the first user is used.
