Function Documentation

ailayer_leaky_relu_q7_avr_pgm()

ailayer_t* ailayer_leaky_relu_q7_avr_pgm	(	ailayer_leaky_relu_q7_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a Leaky ReLU layer with the Q7 AVR PGM implementation.

The quantization parameters of the result tensor of the input layer must be defined constant in program memory (PROGMEM). The layer configuration is the same as with ailayer_leaky_relu_q7_default().

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 (alpha * min(input_layer.result), max(input_layer.result)].

Example: Create the layer structure of a pre-trained model (qparams must be set manually):
In C:

ailayer_leaky_relu_q7_t leaky_relu_layer = {
    .alpha = AISCALAR_Q7(0.01f, 7, 0)
};

In C, C++ and on Arduino:

ailayer_leaky_relu_q7_t leaky_relu_layer = AILAYER_LEAKY_RELU_Q7_M(AISCALAR_Q7(0.01f, 7, 0));

Example: Initialize and connect the layer:

x = ailayer_leaky_relu_q7_avr_pgm(&leaky_relu_layer, x);

Parameters

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

Returns

The (successfully) initialized layer structure.
