relu

整流线性单位函数(Rectified Linear Unit, ReLU),又称修正线性单元, 是一种人工神经网络中常用的激励函数(activation function),通常指代以斜坡函数及其变种为代表的非线性函数。 比较常用的线性整流函数有斜坡函数 = (,) ,以及带泄露整流函数 (Leaky ReLU),其中 为神经元(Neuron)的输入。

Leaky ReLU has a small slope for negative values, instead of altogether zero. For example, leaky ReLU may have y = 0.01x when x < 0. Parametric ReLU (PReLU) is a type of leaky ReLU that, instead of having a predetermined slope like 0.01, makes it

ReLU激活函数 传统神经网络中最常用的两个激活函数,Sigmoid系(Logistic-Sigmoid、Tanh-Sigmoid)被视为神经网络的核心所在。从数学上来看,非线性的Sigmoid函数对中央区的信号增益较大,对两侧区的信号增益小,在信号的特征空间映射上,有很好的

比如说relu, sigmoid, tanh. 将这些掰弯利器嵌套在原有的结果之上, 强行把原有的线性结果给扭曲了. 使得输出结果 y 也有了非线性的特征. 举个例子, 比如我使用了 relu 这个掰弯利器, 如果此时 Wx 的结果是1, y 还将是1, 不过 Wx 为-1的时候, y 不再是-1, 而会是0.

それが「ReLu」のアプローチです。 ReLuは「0より大きければそのまま、0より小さければ0に置き換えて」出力します。 つまり、マイナスの数字をノイズとみなして切り捨てることで、より特徴をつかみやすくする効果を期待するものなわけです。
