LEARNING DEVICE, LEARNING METHOD, AND LEARNING PROGRAM

Title:

LEARNING DEVICE, LEARNING METHOD, AND LEARNING PROGRAM

Document Type and Number:

WIPO Patent Application WO/2024/100854

Kind Code:

A1

Abstract:

This learning device trains an AI model using a dataset in which each piece of data is given a mnemonic code corresponding to a label of that piece of data. Thereafter, the learning device uses the mnemonic code for each label to calculate the diagonal component of the F matrix (pseudo Fisher information matrix) with respect to each label learned by the AI model. Next, the learning device determines noise to impose on a parameter of the AI model on the basis of the value of the diagonal component of the pseudo F matrix with respect to a label to be forgotten and the value of the diagonal component of the F matrix with respect to a label not to be forgotten. The learning device then updates the parameter by imposing the determined noise on the parameter of the AI model.
