Function Documentation

ailayer_elu_calc_result_tensor_params_q31_default()

void ailayer_elu_calc_result_tensor_params_q31_default

(

ailayer_t *

self

)

Calculate and set the quantization parameters for the result tensor of the ELU Q31 default implementation.

Implementation of ailayer.calc_result_tensor_params.

The quantization parameters are pre-defined and the same as in the corresponding math function aimath_q31_default_elu().

Parameters

*self

The layer structure

ailayer_elu_calc_result_tensor_params_q7_default()

void ailayer_elu_calc_result_tensor_params_q7_default

(

ailayer_t *

self

)

Calculate and set the quantization parameters for the result tensor of the ELU Q7 default implementation.

Implementation of ailayer.calc_result_tensor_params.

The quantization parameters are pre-defined and the same as in the corresponding math function aimath_q7_default_elu().

Parameters

*self

The layer structure

ailayer_elu_f32_default()

ailayer_t* ailayer_elu_f32_default	(	ailayer_elu_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect an ELU layer with the F32 default implementation.

Example: Create the layer structure:
In C:

ailayer_elu_f32_t elu_layer = {
    .alpha = 1.0f
};

In C, C++ and on Arduino:

ailayer_elu_f32_t elu_layer = AILAYER_ELU_F32_A(1.0f);

Example: Initialize and connect the layer:

x = ailayer_elu_f32_default(&elu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.

ailayer_elu_q31_default()

ailayer_t* ailayer_elu_q31_default	(	ailayer_elu_q31_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a ELU layer with the Q31 default implementation.

The quantization parameters of the result tensor are automatically set to {shift = input_layer.result.shift, zero_point = input_layer.result.zero_point} because the output values are in the interval (max(-alpha, min(input_layer.result)), max(input_layer.result)].

Example: Create the layer structure:
In C:

ailayer_elu_q31_t elu_layer = {
    .alpha = AISCALAR_Q31(1.0f, 2, 0)
};

In C, C++ and on Arduino:

ailayer_elu_q31_t elu_layer = AILAYER_ELU_Q31_M(AISCALAR_Q31(1.0f, 2, 0));

Example: Initialize and connect the layer:

x = ailayer_elu_q31_default(&elu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.

ailayer_elu_q7_default()

ailayer_t* ailayer_elu_q7_default	(	ailayer_elu_q7_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a ELU layer with the Q7 default implementation.

The quantization parameters of the result tensor are automatically set to {shift = input_layer.result.shift, zero_point = input_layer.result.zero_point} because the output values are in the interval (max(-alpha, min(input_layer.result)), max(input_layer.result)].

Example: Create the layer structure:
In C:

ailayer_elu_q7_t elu_layer = {
    .alpha = AISCALAR_Q7(1.0f, 2, 0)
};

In C, C++ and on Arduino:

ailayer_elu_q7_t elu_layer = AILAYER_ELU_Q7_M(AISCALAR_Q7(1.0f, 2, 0));

Example: Initialize and connect the layer:

x = ailayer_elu_q7_default(&elu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.
