fann_create_sparse_array

    (PECL fann >= 1.0.0)

    fann_create_sparse_array — Creates a standard backpropagation neural network, which is not fully connected using an array of layer sizes

    Description

    fann_create_sparse_array(float $connection_rate, int $num_layers, array $layers): resource

    Creates a standard backpropagation neural network, which is not fully connected using an array of layer sizes.

    Parameters

    connection_rate

    The connection rate controls how many connections there will be in the network. If the connection rate is set to 1, the network will be fully connected, but if it is set to 0.5 only half of the connections will be set. A connection rate of 1 will yield the same result as fann_create_standard().

    num_layers

    The total number of layers including the input and the output layer.

    layers

    An array of layer sizes.

    Return Values

    Returns a neural network resource on success, or false on error.
