zeros

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

Create an array filled with zeros.

This is a non-backpropagable function.

Methods

zeros

$g->zeros(
    ArrayShape|array $shape,
    int $dtype,
) : Variable

Create and execute the function in the builder method

Arguments

  • shape: The arguments is array or ArrayShape.
  • dtype: constant integer. the array’s data type.
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]],dtype:NDArray::float32);
$c = $nn->with($tape=$g->GradientTape(),function() use ($g,$x) {
    return $g->zeros($g->shape($x),NDArray::int32);
});
