  • namespace: Rindow\NeuralNetworks\Gradient\Func
  • classname: ZerosLike

Create an array filled with zeros, in the same format and data type as the input array.

This is a non-backpropagable function.

Methods

zerosLike

$g->zerosLike(
    Variable|NDArray $x,
) : Variable

Create and execute the function in the builder method

Arguments

  • x: The arguments is Variable or NDArray.
use Rindow\Math\Matrix\MatrixOperator;
use Rindow\NeuralNetworks\Builder\NeuralNetworks;
$mo = new MatrixOperator();
$nn = new NeuralNetworks($mo);
$g = $nn->gradient();
$x = $g->Variable([[1,2],[3,4]]);
$c = $nn->with($tape=$g->GradientTape(),function() use ($g,$x) {
    return $g->zerosLike($x);
});
