Variable

  • namespace: Rindow\NeuralNetworks\Gradient

Converts a Variable or NDArray to an NDArray. If a Mask tensor is included, the Mask tensor will also be removed. Use this when you want to use the output result of the automatic differentiation formula in normal LinearAlgebra calculations.

Methods

constructor

$g->ndarray(
    NDArray $variable,
)

Arguments

  • value: Variable or NDArray or MaskedNDArray.

Examples

use Rindow\Math\Matrix\MatrixOperator;
use Rindow\NeuralNetworks\Builder\NeuralNetworks;
$mo = new MatrixOperator();
$nn = new NeuralNetworks($mo);
$g = $nn->gradient();

$variable_a = $g->Variable([1,2]);

$value_a = $g->ndarray($variable_a)
