# tensorflow::ops::ResourceApplyAddSign

`#include <training_ops.h>`

Update '\*var' according to the AddSign update.

## Summary

m_t \<- beta1 \* m_{t-1} + (1 - beta1) \* g update \<- (alpha + sign_decay \* sign(g) \*sign(m)) \* g variable \<- variable - lr_t \* update

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.0/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- var: Should be from a Variable().
- m: Should be from a Variable().
- lr: Scaling factor. Must be a scalar.
- alpha: Must be a scalar.
- sign_decay: Must be a scalar.
- beta: Must be a scalar.
- grad: The gradient.

Optional attributes (see `https://www.tensorflow.org/versions/r2.0/api_docs/cc/struct/tensorflow/ops/resource-apply-add-sign/attrs#structtensorflow_1_1ops_1_1_resource_apply_add_sign_1_1_attrs`):

- use_locking: If `True`, updating of the var and m tensors is protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

Returns:

- the created `https://www.tensorflow.org/versions/r2.0/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation`
