Abstract:

As a significant role in image recognition, neural network can be disturbed by adversarial samples, resulting in recognition errors. Considering that classical adversarial sample generation methods are limited in terms of constraint variables and measurement metrics, this paper puts forward an adversarial sample generation method based on spatial and energy dimensions constrained by cosine similarity, which generates an adversarial sample by spatially translating and rotating the original sample and superimposing a certain strength of Gaussian noise on the energy dimension. Compared with the classic artificial perturbations, rotational shift of spatial dimension and noise of energy dimension exist in large probability in picture generation, transmission, and processing, therefore, the generation of adversarial samples is more natural. The experimental results demonstrate that adversarial sample with both energy and spatial dimensions acting simultaneously is more effective than adversarial sample with only spatial dimensions.
