adversarial example — images to which an elaborate perturbation is maliciously added could deceive a network, which entails the study of countermeasures urgently. However, existing solutions suffer ...

We present an example of a positive function g with a positive Fourier transform g/spl circ/ and reasonable smoothness and decay properties such that (-1)/sup nm/exp(/spl pi/itm)g(t-n), n, m/spl ...
