Document Type and Number:

Japanese Patent JP2023182380

Kind Code:

A

Abstract:

To provide a machine learning method, an information processing system, an information processing device, a server and a program capable of generating a model that has a high performance for unknown other facilities even if pieces of data on multiple facilities cannot be shared outside the facility when a prediction model utilized for information recommendation is learnt.SOLUTION: An information processing system that includes one or more processors is configured to: learn a local model that predicts an activity for the item of a user for each facility by use of data for each facility collected at each of a plurality of facilities; evaluate a difference between the models of parameters of the learnt local model for each facility; and correct the learning of the local model so as to reduce the difference between the models on the basis of the evaluation result.SELECTED DRAWING: Figure 15
