NN_elu()

void NN_elu	(	Tensor *	y,
		const Tensor *	x,
		float	alpha
	)

Applies the Exponential Linear Unit (ELU) function, element-wise.

The ELU function is defined as:

ELU(x) = x, if x > 0 alpha * (exp(x) - 1), if x <= 0

Parameters

y	output tensor
x	input tensor
alpha	the alpha value for the ELU formulation
