tf.compat.v1.raw_ops.ResourceSparseApplyRMSProp

tf.raw_ops.ResourceSparseApplyRMSProp(
    var, ms, mom, lr, rho, momentum, epsilon, grad, indices, use_locking=False,
    name=None
)

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

Args
var	A Tensor of type resource. Should be from a Variable().
ms	A Tensor of type resource. Should be from a Variable().
mom	A Tensor of type resource. Should be from a Variable().
lr	A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. Scaling factor. Must be a scalar.
rho	A Tensor. Must have the same type as lr. Decay rate. Must be a scalar.
momentum	A Tensor. Must have the same type as lr.
epsilon	A Tensor. Must have the same type as lr. Ridge term. Must be a scalar.
grad	A Tensor. Must have the same type as lr. The gradient.
indices	A Tensor. Must be one of the following types: int32, int64. A vector of indices into the first dimension of var, ms and mom.
use_locking	An optional bool. Defaults to False. 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.
name	A name for the operation (optional).

Returns
The created Operation.
