Document Type and Number:
Japanese Patent JP2023156633
Kind Code:
A
Abstract:
To provide an inference device, an ensemble model generation device, an inference method, an ensemble model generation method, and a program that generate an ensemble model with improved classification robustness and generalization performance.SOLUTION: An ensemble model generation device 10 includes: a feature extraction unit 12 that has a plurality of feature extractors hwi that extract different features from input data; one identification unit 14 that identifies, on the basis of each of a plurality of feature quantities obtained by the feature extraction unit 12, data and outputs a plurality of identification results; a loss calculation unit 16 that calculates a loss between the plurality of identification results output from the identification unit 14 and a teacher label; and a feature extractor gradient calculation unit 20 that is used to update parameters of a plurality of feature extractors hwi, and calculates the loss obtained by the loss calculation unit 16 and a gradient having a regularization term that promotes diversification of the feature quantities. The ensemble model generation device uses the gradient calculated by the feature extractor gradient calculation unit 20 and updates a parameter of the feature extractor 12.SELECTED DRAWING: Figure 1
