Webx x x and y y y are tensors of arbitrary shapes with a total of n n n elements each.. The mean operation still operates over all the elements, and divides by n n n.. The division by n n n can be avoided if one sets reduction = 'sum'..

Loss function - Wikipedia
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 … See more 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 … See more 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 ∈ … See more • Bayesian regret • Loss functions for classification • Discounted maximum loss • Hinge loss See more In many applications, objective functions, including loss functions as a particular case, are determined by the problem formulation. In … See more 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 See more 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 … See more • Aretz, Kevin; Bartram, Söhnke M.; Pope, Peter F. (April–June 2011).
