# tensorflow::ops::ResourceSparseApplyProximalAdagrad

`#include <training_ops.h>`

Sparse update entries in '\*var' and '\*accum' according to FOBOS algorithm.

## Summary

That is for rows we have grad for, we update var and accum as follows: accum += grad \* grad prox_v = var prox_v -= lr \* grad \* (1 / sqrt(accum)) var = sign(prox_v)/(1+lr\*l2) \* max{\|prox_v\|-lr\*l1,0}

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- var: Should be from a Variable().
- accum: Should be from a Variable().
- lr: Learning rate. Must be a scalar.
- l1: L1 regularization. Must be a scalar.
- l2: L2 regularization. Must be a scalar.
- grad: The gradient.
- indices: A vector of indices into the first dimension of var and accum.

Optional attributes (see `https://www.tensorflow.org/versions/r1.15/api_docs/cc/struct/tensorflow/ops/resource-sparse-apply-proximal-adagrad/attrs#structtensorflow_1_1ops_1_1_resource_sparse_apply_proximal_adagrad_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:

- the created `https://www.tensorflow.org/versions/r1.15/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation`
