# tensorflow::ops::SparseApplyAdadelta Class Reference

# tensorflow::ops::SparseApplyAdadelta

`#include <training_ops.h>`

var: Should be from a Variable().

## Summary

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- accum: Should be from a Variable().
- accum_update: : Should be from a Variable().
- lr: Learning rate. Must be a scalar.
- rho: Decay factor. Must be a scalar.
- epsilon: Constant factor. Must be a scalar.
- grad: The gradient.
- indices: A vector of indices into the first dimension of var and accum.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r2.3/api_docs/cc/struct/tensorflow/ops/sparse-apply-adadelta/attrs#structtensorflow_1_1ops_1_1_sparse_apply_adadelta_1_1_attrs`):

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

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: Same as "var".
