It would be difficult to create such persuasive adversarial examples in this case. Humans can recognize images well, so it's obvious for us that those adversarial examples are nowhere near what neural net thinks they are. It would not

Title is misleading. The article only describes univariate analysis (screening of independent variables). One can build a model to predict churn from those independent variables (e.g., by just adding them up), but then there's out-of-t
