We hypothesize that for attacks to be transferrable, it is sufficient if the proxy can approximate the target model in the neighborhood of the harmful query.

To exploit ASR models in real-world, black-box settings, an adversary can leverage the transferability property, i. e. that an adversarial sample produced for a proxy ASR can also fool a different remote ASR.

Finally, with sparsity we can measure increases in robustness that do not affect accuracy: we show for example that data augmentation can by itself increase adversarial robustness, without using adversarial training.

We apply adaptive versions of state-of-the-art attacks, such as the Imperceptible ASR attack, to our model, and show that our strongest defense is robust to all attacks that use inaudible noise, and can only be broken with very high distortion.

Deploying deep learning models, comprising of non-linear combination of millions, even billions, of parameters is challenging given the memory, power and compute constraints of the real world.

In this paper, we propose the use of in-training matrix factorization to reduce the model size for neural machine translation.
