This is a ramp function. This activation function has been argued to be more biologically plausible than the widely used logistic sigmoid (which is inspired by probability theory; see logistic regression) and its more practical counterpart, the hyperbolic tangent. The rectifier is, , the most popular activation function for deep neural networks. A unit employing the rectifier is also called a rectified linear unit (ReLU).〔 A smooth approximation to the rectifier is the analytic function :$f(x)\; =\; \backslash ln(1\; +\; e^x)$ which is called the softplus function.〔C. Dugas, Y. Bengio, F. Bélisle, C. Nadeau, R. Garcia, NIPS'2000, (2001),(Incorporating Second-Order Functional Knowledge for Better Option Pricing )〕 The derivative of softplus is $f\text{'}(x)\; =\; e^x\; /\; (e^x+1)\; =\; 1\; /\; (1\; +\; e^)$, i.e. the logistic function. Rectified linear units find applications in computer vision using deep neural nets.〔 == Variants == 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「Rectifier (neural networks)」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.
