We investigate the robustness properties of ResNeXt class image recognition models trained with billion scale weakly supervised data (ResNeXt WSL models). ...
Remarkably, the ResNeXt WSL models even achieve a limited degree of adversarial robustness against state-of-the-art white-box attacks (10-step PGD attacks). ...

Our finding supports the hypothesis that perceptually-aligned gradients may be a general property of robust classifiers. ...
For a standard convolutional neural network, optimizing over the input pixels to maximize the score of some target class will generally produce a grainy-looking version of the original image. ...
This finding supports the conjecture in [9, 10, 11] that perceptually-aligned gradients may be a general property of robust classifiers, and not only a curious consequence of adversarial training. ...

We show that they are robust in the sense that many variants of each signature (where in particular operations are defined by quantifier-free formulas, a quite flexible framework) yield the same notions ...
Once the set of finite graphs is equipped with an algebra structure (arising from the definition of operations that generalize the concatenation of words), one can define the notion of a recognizable set ...
This gives immediately many closure properties for context-free sets of graphs, via the use of MS logic as a specification language for graph properties. ...
