Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A processor-implemented classification method, comprising: generating defensive noise from the input image;
generating a combined image by combining the input image and the defensive noise; and
outputting a classification result by inputting the combined image to a classifier,
wherein the defensive noise is generated by a defensive noise generator trained to reduce a total loss value in a training process, and wherein the total loss value is determined using a total loss function by inputting a denoised noised training image and a denoised training image to the classifier,
wherein the denoised noised training image is a result of applying adversarial noise generated by an adversarial noise generator and the defensive noise generated by the defensive noise generator to a training image, and wherein the denoised training image is a result of applying the defensive noise to the training image.
