Robustness properties of Facebook's ResNeXt WSL models [article]

A. Emin Orhan
2019 arXiv   pre-print
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).  ...  Acknowledgments We are very grateful to the authors of Geirhos et al.  ...

Robustness properties of a large-amplitude, high-frequency extremum seeking control scheme [article]

Raik Suttner, Sergey Dashkovskiy
2021 arXiv   pre-print
We analyze stability and robustness properties of an extremum seeking scheme that employs oscillatory dither signals with sufficiently large amplitudes and frequencies.  ...  A suitable change of coordinates followed by an averaging procedure reveals that the closed-loop system approximates the behavior of an averaged system.  ...  Note that Theorem 1 provides robust stability properties of the pull-back system (21) .  ...

Are Perceptually-Aligned Gradients a General Property of Robust Classifiers? [article]

Simran Kaur, Jeremy Cohen, Zachary C. Lipton
2019 arXiv   pre-print
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.  ...

The recognizability of sets of graphs is a robust property [article]

Bruno Courcelle
2006 arXiv   pre-print
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.  ...

A robustness property of DOA estimators based on covariance

J.-F. Cardoso, E. Moulines
1994 IEEE Transactions on Signal Processing  
Abstract| A simple general formula is derived under a Gaussian model for the asymptotic covariance of directionof-arrival (DOA) estimators based on the covariance of the sensor array data.  ...  It is then established that the same formula remains valid for a wide class of statistical models for source signals.  ...  We have established`asymptotic robustness' by combining two properties.  ...
