A variant for classification is also sometimes used. ==Definition== The Huber loss function describes the penalty incurred by an estimation procedure . Huber (1964) defines the loss function piecewise by :$$ L_\delta (a) = \begin \frac & \text |a| \le \delta, \\ \delta (|a| - \frac\delta), & \text \end This function is quadratic for small values of , and linear for large values, with equal values and slopes of the different sections at the two points where $|a|\; =\; \backslash delta$. The variable often refers to the residuals, that is to the difference between the observed and predicted values $a\; =\; y\; -\; f(x)$, so the former can be expanded to〔 Compared to Hastie ''et al.'', the loss is scaled by a factor of ½, to be consistent with Huber's original definition given earlier.〕 :$$ L_\delta(y, f(x)) = \begin \frac(y - f(x))^2 & \textrm |y - f(x)| \le \delta, \\ \delta\, |y - f(x)| - \frac\delta^2 & \textrm \end 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Huber loss」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
