FEDERATED LEARNING SYSTEM, FEDERATED LEARNING METHOD AND FEDERATED LEARNING PROGRAM

Document Type and Number:

Japanese Patent JP2023177487

Kind Code:

A

Abstract:

To provide a suitable model for each client terminal that participates in federated learning.SOLUTION: A federated learning system has a plurality of client terminals having a learning data set and a server, the learning data set has a data sample including a client ID, a first explanatory variable and a first objective variable, and the system executes calculation processing through the client terminals, and executes first federated learning processing that repeats first learning processing through the client terminals and first integration processing through the server. In the calculation processing, the client terminal inputs the data sample in a similarity calculation mode and calculates similarity between the data sample and a plurality of learning data sets. In the first learning processing, the client terminal learns an individual analysis model on the basis of similarity between a specific learning data set and specific similarity. In the first integration processing, the server integrates first learning results from the plurality of client terminals, and generates first integration information about an integrated individual analysis model.SELECTED DRAWING: Figure 4
