Document Type and Number:
Japanese Patent JP2023177836
Kind Code:
A
Abstract:
To provide a machine learning system and a method capable of ensuring a high level of security in machine learning.SOLUTION: Each of a plurality of client terminals extracts a first parameter column from a machine learning model on which learning processing has been performed, changes an arrangement of the first parameter column, generates a first fragment parameter column by performing secret sharing on the first parameter column of which the arrangement has been changed, and transmits the first fragment parameter column to a plurality of integration server devices. Each of the plurality of integration server devices changes the arrangement of each of the plurality of first fragment parameter columns received from the plurality of client terminals; and generates a second fragment parameter column by performing integration processing on the plurality of first fragment parameter columns of which the arrangement has been changed. The machine learning model is updated on the basis of a second parameter column decoded from a plurality of second fragment parameter columns.SELECTED DRAWING: Figure 5
