fann_create_sparse

Creates a standard backpropagation neural network, which is not fully connected

Description

resource fann_create_sparse(
    float $connection_rate,
    int $num_layers,
    int $num_neurons1,
    int $num_neurons2,
    int ...$num_neuronsN
)

Creates a standard backpropagation neural network, which is not fully connected.

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.

num_neurons1

Number of neurons in the first layer.

num_neurons2

Number of neurons in the second layer.

num_neuronsN

Number of neurons in other layers.

Return Values

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