The centered RMSProp algorithm uses an estimate of the centered second moment
(i.e., the variance) for normalization, as opposed to regular RMSProp, which
uses the (uncentered) second moment. This often helps with training, but is
slightly more expensive in terms of computation and memory.
Note that in dense implementation of this algorithm, mg, ms, and mom will
update even if the grad is zero, but in this sparse implementation, mg, ms,
and mom will not update in iterations during which the grad is zero.
A mutable Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, qint16, quint16, uint16, complex128, half, uint32, uint64.
Should be from a Variable().
mg
A mutable Tensor. Must have the same type as var.
Should be from a Variable().
ms
A mutable Tensor. Must have the same type as var.
Should be from a Variable().
mom
A mutable Tensor. Must have the same type as var.
Should be from a Variable().
lr
A Tensor. Must have the same type as var.
Scaling factor. Must be a scalar.
rho
A Tensor. Must have the same type as var.
Decay rate. Must be a scalar.
momentum
A Tensor. Must have the same type as var.
epsilon
A Tensor. Must have the same type as var.
Ridge term. Must be a scalar.
grad
A Tensor. Must have the same type as var. 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, mg, ms, and mom tensors is
protected by a lock; otherwise the behavior is undefined, but may exhibit less
contention.
