Detailed Description

General ELU layer struct.

Field Documentation

d_elu

void(* d_elu) (const aitensor_t *x, const void *alpha, aitensor_t *result)

Required math function: Derivative of ELU.

Requires a math function that calculates the element wise ELU derivative of a tensor:

\[ result_{i} = \begin{cases} \alpha \cdot e^{x_i} & \text{if } x_i < 0\\ 1 & \text{if } x_i \geq 0 \end{cases} \]

Parameters

x	N-dimensional tensor (input)
result	N-dimensional tensor (output)

elu

void(* elu) (const aitensor_t *x, const void *alpha, aitensor_t *result)

Required math function: ELU.

Requires a math function that calculates the element wise ELU of a tensor:

\[ result_{i} = \begin{cases} \alpha \cdot (e^{x_i} - 1) & \text{if } x_i < 0 \\ x_i & \text{if } x_i \geq 0 \end{cases} \]

Parameters

x	N-dimensional tensor (input)
result	N-dimensional tensor (output)

multiply

void(* multiply) (const aitensor_t *a, const aitensor_t *b, aitensor_t *result)

Required math function: Element wise tensor multiplication.

Requires a math function that multiplies two tensors element wise:

\[ result = a \circ b \]
