Is There a Single Pixl Attack in Machine Learning?

A lot of research is going into at the moment, which is called adversarial machine learning. Bad actors who do have a lot of experience can actually extract sensitive information about the data that was used to build the model. There's a research team out of google called clever hans that does amazing work in this space. But it gets very scary. Like, you know, you can have something called a single pixl attack. You can suddenly go from accurately classifying a high confidence level to classifying incorrectly, but with an even higher confidence level. It's very scary, it is.
