Aggregating Forecasts of Chance from Incoherent and Abstaining Experts
Linear averaging is a popular method for combining forecasts of chance, but it is of limited use in the context of incoherent or abstaining judges. Recently proposed, the coherent approximation principle (CAP) generalizes linear averaging to have wider applicability yet suffers from computational intractability in cases of interest. This paper proposes a unified framework that views CAP and lin...
متن کاملOn Abstaining Classifiers
Contrary to standard non-abstaining classifiers, abstaining classifiers have the choice to label an instance with any of the given class labels or to refrain from giving a classification in order to improve predictive performance. Our interest in abstaining classifiers is motivated by applications for which reliable predictions can only be obtained for a fraction of instances such as, for examp...
متن کاملAggregating Probabilistic Forecasts from Incoherent and Abstaining Experts
D makers often rely on expert opinion when making forecasts under uncertainty. In doing so, they confront two methodological challenges: the elicitation problem, which requires them to extract meaningful information from experts; and the aggregation problem, which requires them to combine expert opinion by resolving disagreements. Linear averaging is a justifiably popular method for addressing ...

متن کاملCost Curves for Abstaining Classifiers
We present abstention cost curves, a new three-dimensional visualization technique to illustrate the strengths and weaknesses of abstaining classifiers over a broad range of cost settings. The three-dimensional plot shows the minimum expected cost over all ratios of false-positive costs, false-negative costs and abstention costs. Generalizing Drummond and Holte’s cost curves, the technique allo...
