The video example of a turtle being misclassified as a rifle is pretty scary https://www.youtube.com/watch?v=piYnd_wYlT8

We're approaching a world where AI will be more and more relied upon in dangerous situations. Imagine someone getting killed for something ridiculous like inadvertently holding an adversarial example. Public trust would have a hard time recovering.

I wonder how sensitive these results are. I mean, if you run one more learning round of the network, does the rifle turn to turtle in the eyes of the network immediately so that you would need to generate a new turtle for every single network? Or does that turtle look like rifle for all current neural networks? Or, most likely, somewhere in between?

This would never be the case with humans, right? No.

Would adding random noise to an image before running it through the classifier mitigate these kinds of attacks?

If you don't change the data, why would the network change its results with just some more learning iterations? It's already converging.

No, ironically because classifiers are trained to be robust to noise. Adversarial examples are generated by altering the original in one specific dimension of a high-dimensional vector space. Random noise is vanishingly unlikely to undo that transformation, so the classification will stay wrong.
