'''Loss function surrogates for classification''' are computationally feasible [[loss functions]] representing the price we will pay for inaccuracy in our predictions in classification problems. <ref>{{cite doi|10.1162/089976604773135104}}</ref> Specifically, if <math>g: X \mapsto</math> {-1,1} represents the mapping of a vector <math>\vec{x} \in X</math> to a class label <math>y \in </math>{-1,1}, we wish to find a function <math>f: X \mapsto \mathbb{R}</math> which best approximates the true mapping <math>g</math>.
