#include <training_ops.h>
Update '*var' by subtracting 'alpha' * 'delta' from it.
Summary
Arguments:
- scope: A Scope object
- var: Should be from a Variable().
- alpha: Scaling factor. Must be a scalar.
- delta: The change.
Optional attributes (see Attrs):
- use_locking: If
True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
Returns:
