tensorflow::ops::ApplyGradientDescent

#include <training_ops.h>

Обновить '*var', вычтя из него 'alpha' * 'delta'.

Summary

Arguments:

scope: An Scope object
var: Должен быть получен из Variable().
alpha: Коэффициент масштабирования. Должен быть скалярным.
delta: Изменение.

Optional attributes (see Attrs):

use_locking: Если True, вычитание будет защищено блокировкой; в противном случае поведение не определено, но может характеризоваться меньшим конфликтом.

Returns:

Output: Идентично "var".
