Title:
Classification methods with a reject option.

Abstract:
In this talk I will discuss binary classification methods that have a 
built-in reject option, in which case no decision is made at a lower 
cost than that of misclassification. The main focus of the talk are 
empirical risk minimizers based on convex surrogate loss functions. I 
will present necessary and sufficient conditions on the loss function 
for infinite sample consistency and I will show that fast rates of 
convergence of the statistical error can be achieved for empirical risk 
minimizers under a generalized Mammen-Tsybakov noise or margin condition.
