One thing I don't agree with is that notion of robustness is human specified, when they clearly measure robustness of a given feature before classification is changed. Robustness is a systems statistical notion of amount or degrees of freedom of state perturbation required to change output, also taking into consideration the magnitude of change. It is related to but not same as system theoretical stability. There's nothing human about the definition. Robust features need not be human derived. The desired degree of robustness vs absolute accuracy or precision or bias trade-off is human specified but generally the trade-off is not huge between these variables.
