Re: Is it a bug?
I assume you mean "emits"? As long as backpropagation applies the right weight, it will.
It does remind me of the ai version of a honeypot.
A paper was making the rounds recently that described a universal method to fool, iirc, cnn, by applying a distortion field over an image. The images remained recognizable by humans. What seemed to be forgotten was that the algorithm is now a part of new training sets which will make the systems more robust.
