Detailed Description

General Stochastic Gradient Descent (SGD) optimizer struct.

Field Documentation

scalar_mul

void(* scalar_mul) (const void *scalar, const aitensor_t *a, aitensor_t *result)

Required math function: Multiplication of a scalar with a tensor.

Requires a math function that multiplies a scalar with a tensor:

\[ result = scalar \cdot a \]

tensor_add

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

Required math function: Element wise tensor addition.

Requires a math function that adds two tensors element wise:

\[ result = a + b \]

tensor_sub

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

Required math function: Element wise tensor subtraction.

Requires a math function that subtracts two tensors element wise:

\[ result = a - b \]

zero_tensor

void(* zero_tensor) (aitensor_t *tensor)

Required math function: Sets the elements of a tensor to zero.

Requires a math function that sets the elements of the given tensor to zero (or to the zero_point):

\[ tensor_i = 0 \]
