Web14 de out. de 2024 · Angular penalty loss functions in Pytorch (ArcFace, SphereFace, Additive Margin, CosFace) pytorch face-recognition metric-learning speaker-recognition … In mathematical optimization and decision theory, a loss function or cost function (sometimes also called an error function) is a function that maps an event or values of one or more variables onto a real number intuitively representing some "cost" associated with the event. An optimization problem seeks … Ver mais Regret Leonard J. Savage argued that using non-Bayesian methods such as minimax, the loss function should be based on the idea of regret, i.e., the loss associated with a decision should be … Ver mais A decision rule makes a choice using an optimality criterion. Some commonly used criteria are: • Minimax: Choose the decision rule with the lowest worst loss — that is, minimize the worst-case (maximum possible) loss: a r g m i n δ max θ ∈ … Ver mais • Bayesian regret • Loss functions for classification • Discounted maximum loss Ver mais • Aretz, Kevin; Bartram, Söhnke M.; Pope, Peter F. (April–June 2011). "Asymmetric Loss Functions and the Rationality of Expected Stock Returns" Ver mais In many applications, objective functions, including loss functions as a particular case, are determined by the problem formulation. In other situations, the decision maker’s … Ver mais In some contexts, the value of the loss function itself is a random quantity because it depends on the outcome of a random variable X. Statistics Both frequentist and Bayesian statistical theory involve … Ver mais Sound statistical practice requires selecting an estimator consistent with the actual acceptable variation experienced in the context of a particular applied problem. Thus, in the applied use of loss functions, selecting which statistical method to use to model an applied … Ver mais

WebTripletMarginLoss. Creates a criterion that measures the triplet loss given an input tensors x1 x1, x2 x2, x3 x3 and a margin with a value greater than 0 0 . This is used for measuring a relative similarity between samples. A triplet is composed by a, p and n (i.e., anchor, positive examples and negative examples respectively).
