Hinge rank loss
WebbThis loss is used for measuring whether two inputs are similar or dissimilar, using the cosine distance, and is typically used for learning nonlinear embeddings or semi-supervised learning. Thought of another way, 1 minus the cosine of the angle between the two vectors is basically the normalised Euclidean distance. In machine learning, the hinge loss is a loss function used for training classifiers. The hinge loss is used for "maximum-margin" classification, most notably for support vector machines (SVMs). For an intended output t = ±1 and a classifier score y, the hinge loss of the prediction y is defined as Visa mer While binary SVMs are commonly extended to multiclass classification in a one-vs.-all or one-vs.-one fashion, it is also possible to extend the hinge loss itself for such an end. Several different variations of … Visa mer • Multivariate adaptive regression spline § Hinge functions Visa mer

Hence, the examples with ranks r i ≤ ¯θget classified as negatives, and the examples with ranks r i ≥ ¯θ+1 as positives. Now we can present Proposition 1.
