Abstract
The risk evaluation apparatus evaluates the risk of a machine learning model. The risk evaluation apparatus includes a recording unit, a loss function regression model acquirer, an attack noise addition unit, an error acquisition unit, and an evaluation unit. The recording unit records a set of predetermined loss functions and a set of pairs of data and labels predetermined. The loss function regression model acquirer determines a regression model of the loss function in the vicinity of data by nonparametric regression. The attack noise addition unit creates attack data that is an Adversarial Example using the regression model. The error acquisition unit determines the error between the output of the machine learning model when the data is input and the output of the machine learning model when the attack data is input. The evaluation unit evaluates the risk based on a set of errors.
