Function Documentation

ailayer_maxpool2d_cfirst_f32_default()

ailayer_t* ailayer_maxpool2d_cfirst_f32_default	(	ailayer_maxpool2d_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a MaxPool2D layer (channels first) with the F32 default implementation.

Code examples are given in the description of ailayer_maxpool2d_f32_default().

Parameters

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

Returns

The (successfully) initialized layer structure.

ailayer_maxpool2d_chw_f32_default()

ailayer_t* ailayer_maxpool2d_chw_f32_default	(	ailayer_maxpool2d_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a MaxPool2D layer (channels first) with the F32 default implementation.

Code examples are given in the description of ailayer_maxpool2d_f32_default().

Parameters

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

Returns

The (successfully) initialized layer structure.

ailayer_maxpool2d_clast_f32_default()

ailayer_t* ailayer_maxpool2d_clast_f32_default	(	ailayer_maxpool2d_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a MaxPool2D layer (channels last) with the F32 default implementation.

Code examples are given in the description of ailayer_maxpool2d_f32_default().

Parameters

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

Returns

The (successfully) initialized layer structure.

ailayer_maxpool2d_f32_default()

ailayer_t* ailayer_maxpool2d_f32_default	(	ailayer_maxpool2d_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a Conv2D layer with the F32 default implementation.

Example: Create the layer structure:
In C:

ailayer_maxpool2d_f32_t maxpool2d_layer = {
    .pool_size =    {2, 2},
    .stride =       {2, 2},
    .padding =      {0, 0}
};

In C, C++ and on Arduino:

ailayer_maxpool2d_t maxpool2d_layer = AILAYER_CONV2D_F32_A(
                                                            /* pool_size =*/    HW(2, 2),
                                                            /* stride =*/       HW(2, 2),
                                                            /* padding =*/      HW(0, 0)
                                                           );

Example: Initialize and connect the layer for data with channels first (all options are equivalent):

maxpool2d_layer.channel_axis = 1;
x = ailayer_maxpool2d_f32_default(&maxpool2d_layer, x);

or

x = ailayer_maxpool2d_cfirst_f32_default(&maxpool2d_layer, x);

or

x = ailayer_maxpool2d_chw_f32_default(&maxpool2d_layer, x);

Example: Initialize and connect the layer for data with channels last (all options are equivalent):

maxpool2d_layer.channel_axis = -1;
x = ailayer_maxpool2d_f32_default(&maxpool2d_layer, x);

or

x = ailayer_maxpool2d_clast_f32_default(&maxpool2d_layer, x);

or

x = ailayer_maxpool2d_hwc_f32_default(&maxpool2d_layer, x);

Parameters

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

Returns

The (successfully) initialized layer structure.

ailayer_maxpool2d_hwc_f32_default()

ailayer_t* ailayer_maxpool2d_hwc_f32_default	(	ailayer_maxpool2d_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a MaxPool2D layer (channels last) with the F32 default implementation.

Code examples are given in the description of ailayer_maxpool2d_f32_default().

Parameters

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

Returns

The (successfully) initialized layer structure.
