- ReLU——Rectified Linear Unit (整流线性单元)
R e L U ( x ) = m a x ( 0 , x ) ReLU(x)=max(0,x) ReLU(x)=max(0,x) - ELU——Exponential linear units(指数线性单元)
E L U ( x ) = { x ; x ≥ 0 a ( e x − 1 ) ; x < 0 ELU(x)=\left\{ \begin{aligned} x ; x\geq0 \\ a(e^x-1);x<0 \end{aligned} \right. ELU(x)={x;x≥0a(ex−1);x<0 - Leaky ReLU
L e a k y R e L U ( x ) = { x ; x ≥ 0 a x ; x < 0 Leaky ReLU(x)=\left\{ \begin{aligned} x ; x\geq0 \\ ax;x<0 \end{aligned} \right. LeakyReLU(x)={x;x≥0ax;x<0
