Enum cogent::Activation [−][src]
Defines the activation of a layer.
Variants
Sigmoid activation functions.
$ A(z)=\frac{1}{1+e^{-z}} $
Tanh activation functions.
$ A(z)=\frac{2}{1+e^{-2z}}-1 $
Softmax activation function.
$ A(\begin{bmatrix}z_1,\dots,z_k\end{bmatrix})=\begin{bmatrix}\frac{e^{z_1}}{\Sigma_{i=1}^k e^{z_i}} & \dots &\frac{e^{z_k}}{\Sigma_{i=1}^k e^{z_i}}\end{bmatrix} $
ReLU activation function.
$ A(z)=max(z,0) $
Implementations
impl Activation
