Binary classification with a reject option

This paper studies two-class (or binary) classification of elements X in Rk that allows for a reject option. Based on n independent copies of the pair of random variables (X,Y) with X ∈ Rk and Y ∈ {0,1}, we consider classifiers f(X) that render three possible outputs: 0, 1 and R. The option R expresses doubt and is to be used for few observations 2/2/ · Binary classification with a reject option We consider the binary classification with a reject option novel scenario where workers have a reject option, so they may skip microtasks they are unable or unwilling to do utilizing the reject option is d>0. Given a classifier with reject option t: X → {−1,1,r}, the appropriate risk function is (3) L d(t):= dP{t(X) = r}+P{t(X) 6= Y,t(X) 6= r}. It is easy to see that the rule minimizing this risk assigns −1,1 or r depending on which of η(x), 1−η(x) or dis smallest
