Learning device, imaging device, and learning method

A learning device for use with an external camera, the learning device comprising:

• a reception circuit that receives a request from the external camera, the request including a target third party evaluator profile information;
• a machine learning processor that (1) retrieves third party evaluated images from an image database using the target third party evaluator profile information in the received request, and (2) performs machine learning using the retrieved third party evaluated images and corresponding evaluations as training data to generate an inference model to infer a relationship between features of the images and evaluations of third parties matching the target third party evaluator profile information;
• and
• a transmission circuit that transmits the generated inference model to the imaging device.

A learning method, comprising:

• receiving a request from an imaging device, the request including a target third party evaluator profile information;
• retrieving third party evaluated images from an image database using the target third party evaluator profile information in the received request;
• performing machine learning using the retrieved third party evaluated images and corresponding evaluations as training date to generate an inference model to infer a relationship between features of the images and evaluations of the third parties matching the target third party evaluator profile information;
• and
• transmitting the generated inference model to the imaging device.

A learning method, comprising:

• retrieving images, that have received a given evaluation from a third party, from an image database;
• performing machine learning using the retrieved images to generate a plurality of inference models;
• receiving, from an imaging device, a request that represents photographs that a user of the imaging device wants;
• selecting an inference model that is most appropriate to the request, from among the plurality of inference models;
• and
• transmitting the selected inference model to the imaging device.

A learning method, comprising:

• receiving a request from an external device, the request including a target third party evaluator profile information;
• retrieving from a database, data that matches the request and that includes evaluation information for which there is a difference in subjective evaluation for each data;
• performing machine learning using groups of the retrieved data to generate an inference model for subjective evaluation prediction;
• and
• transmitting the inference model to the external device.
