A loss of $0.05 is perceived with a much greater utility loss than the utility increase of a comparable gain. Loss aversion is a psychological and economic concept, [ 1] which refers to how outcomes are interpreted as gains and losses where losses are subject to more sensitivity in people's responses compared to equivalent gains acquired. [ 2]
In machine learning and mathematical optimization, loss functions for classification are computationally feasible loss functions representing the price paid for inaccuracy of predictions in classification problems (problems of identifying which category a particular observation belongs to). [ 1] Given as the space of all possible inputs ...
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 preference must be elicited and represented by a scalar-valued function (called also utility function) in a form suitable for optimization — the problem that Ragnar Frisch has highlighted in his Nobel Prize lecture.

Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [ 1][ 2] or network congestion. [ 3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.
Lost is an American science fiction adventure drama television series created by Jeffrey Lieber, J. J. Abrams, and Damon Lindelof that aired on ABC from September 22, 2004, to May 23, 2010, with a total of 121 episodes over six seasons. It contains elements of supernatural fiction, and follows the survivors of a commercial jet airliner flying ...
Huber (1964) defines the loss function piecewise by [ 1] This function is quadratic for small values of a, and linear for large values, with equal values and slopes of the different sections at the two points where . The variable a often refers to the residuals, that is to the difference between the observed and predicted values , so the former ...
Dielectric loss. In electrical engineering, dielectric loss quantifies a dielectric material 's inherent dissipation of electromagnetic energy (e.g. heat). [ 1] It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan (δ). Both refer to the phasor in the complex plane whose real and imaginary parts are ...
Ambiguous loss. Ambiguous loss is a loss that occurs without a significant likelihood of reaching emotional closure or a clear understanding. [ 1][ 2] This kind of loss leaves a person searching for answers, and thus complicates and delays the process of grieving, and often results in unresolved grief. Causes include infertility, termination of ...
