The vulnerability of deep neural networks to adversarial attacks currently represents one of the most challenging open problems in the deep learning field. The NeurIPS 2018 work that obtained the best paper award proposed a new paradigm for defining deep neural networks with continuous internal activations. In this kind of networks, dubbed Neural ODE Networks, a continuous hidden state can be defined via parametric ordinary differential equations, and its dynamics can be adjusted to build representations for a given task, such as image classification. In this paper, we analyze the robustness of image classifiers implemented as ODE Nets to adversarial attacks and compare it to standard deep models. We show that Neural ODE are natively more robust to adversarial attacks with respect to state-of-the-art residual networks, and some of their intrinsic properties, such as adaptive computation cost, open new directions to further increase the robustness of deep-learned models. Moreover, thanks to the continuity of the hidden state, we are able to follow the perturbation injected by manipulated inputs and pinpoint the part of the internal dynamics that is most responsible for the misclassification. |
