ApplyGradientDescent

tensorflow C++ API

tensorflow::ops::ApplyGradientDescent

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 (seeAttrs):

• use_locking: If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

Returns:

• Output : Same as “var”.

Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
• Input var: connect Input node.
• Input alpha: connect Input node.
• Input delta: connect Input node.
• ApplyGradientDescent ::Attrs attrs : Input attrs in value. ex) use_locking_ = false;

Return:

• Output output : Output object of ApplyFtrl class object.

Result:

• std::vector(Tensor) result_output : Returned object of executed result by calling session.
