Binary options, or all-or-nothing options, are an extremely risky investment 1/12/ · This reject option is to be used for those observations for which the conditional class probabilities are close and as such are hard to classify. The authors generalize existing 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 26/4/ · While binary options involve pure speculation, the chances are greater than a coin flip. This means that you are taking more risk than you win. A binary option that is a winner 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 ... read more

An optimal rule has the lowest probability of error at a fixed "reject" probability. In the case of the Bayes optimal rule, the first term is always nonnegative. We also have an extra term involving the rejection probability. Deciding when to reject then becomes identical to the discrete case of the Neyman Pearson Lemma. We can interpret their ratio as the likelihood ratio.

The analogy doesn't quite make sense to me so I think I'm missing something. In particular, I'm trying to formulate the null hypothesis in this context to make the application of the lemma more concrete. The lemma applies for decision making, not just hypothesis testing.
So as you mentioned, the rule which incurs the loss of rejection for sufficiently large values of the ratio is optimal. Really great, thanks a lot. Sign up or log in Sign up using Google.

As seen in Section 2 , several optimization strategies have been proposed. From 10 features onward, the error rate respects the target error constraints and the rejection rate is stabilized at around 0. The target error is set to 0. The dotted line represents the error rate of classifier with no rejection. For Permissions, please email: journals. For the next iteration, this feature will be tested again. Diverse methods from pattern recognition have been used: linear discriminant analysis Dudoit et al.
