Error Function
The term error function has two common mathematical uses. In the theory of special functions, it denotes erf, the entire
function defined for a complex number
This function occurs in integrals involving the normal distribution. In optimization theory, an error function can instead mean an objective function to be minimized. In this usage, it is often also called a loss function (Goodfellow et al. 2016, p. 80). See alsoErf, Loss Function, Objective FunctionExplore with Wolfram|Alpha
