# tensorflow::ops::SparseApplyRMSProp

`#include <training_ops.h>`

Update '*var' according to the RMSProp algorithm.

## Summary

Note that in dense implementation of this algorithm, ms and mom will update even if the grad is zero, but in this sparse implementation, ms and mom will not update in iterations during which the grad is zero.

mean_square = decay * mean_square + (1-decay) * gradient ** 2 Delta = learning_rate * gradient / sqrt(mean_square + epsilon)

\$\$ms <- rho * ms_{t-1} + (1-rho) * grad * grad\$\$ \$\$mom <- momentum * mom_{t-1} + lr * grad / sqrt(ms + epsilon)\$\$ \$\$var <- var - mom\$\$

Arguments:

• scope: A Scope object
• var: Should be from a Variable().
• ms: Should be from a Variable().
• mom: Should be from a Variable().
• lr: Scaling factor. Must be a scalar.
• rho: Decay rate. Must be a scalar.
• epsilon: Ridge term. Must be a scalar.
• indices: A vector of indices into the first dimension of var, ms and mom.

Optional attributes (see `Attrs`):

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

Returns:

• `Output`: Same as "var".
