Detailed Description

General Sigmoid layer struct.

Field Documentation

d_sigmoid

void(* d_sigmoid) (const aitensor_t *sigmoid_x, aitensor_t *result)

Required math function: Derivative of sigmoid.

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

\[ result_{i} = \sigma'(x_{i}) = \sigma(x_{i}) \cdot (1 - \sigma(x_{i})) \]

Parameters

sigmoid_x	N-dimensional tensor with the sigmoid values \( \sigma(x_{i}) \) (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:

\[ result = a \circ b \]

sigmoid

void(* sigmoid) (const aitensor_t *x, aitensor_t *result)

Required math function: Sigmoid.

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

\[ result_{i} = \sigma(x_{i}) = \frac{1}{1 + e^{-x_{i}}} \]

Parameters

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