ArraySpec

  • namespace: Rindow\NeuralNetworks\Gradient\Core
  • class: ArraySpec

A container that combines the shape and dtype information of an NDArray. Unlike an NDArray, it does not have a value. It is used when defining the input specifications of a model.

Methods

constructor

$g->ArraySpec(
    ArrayShape|array $shape,
    ?int $dtype=null,
    ?string $name=null,
) : ArraySpec

Arguments

  • shape: shape of array.
  • dtype: data type of array

shape

public function shape(
) : ArrayShape

Result

  • shape: Returns the value of the ArrayShape type representing the shape of an array.

dtype

public function dtype(
) : int

Result

  • dtype: Returns the array’s data type.

Examples

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

$spec = $g->ArraySpec([1,2],dtype:NDArray::float32);
....
...
$customModel->build($spec);
$customModel->summary();
