Patent ID: 11967124
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A classification apparatus, comprising: at least one processor; and
a memory,
wherein the memory is configured to store a classifier and a preprocessor comprising a defensive noise generator, and
wherein the at least one processor is configured to generate defensive noise from an input image through the defensive noise generator in the preprocessor;
generate a combined image by combining the input image and the defensive noise; and
output-a classification result by inputting the combined image to the 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.
