Update '*var' according to the RMSProp algorithm.
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

Public Methods
public static ResourceSparseApplyRmsProp create (Scope scope, Operand<?> var, Operand<?> ms, Operand<?> mom, Operand<T> lr, Operand<T> rho, Operand<T> momentum, Operand<T> epsilon, Operand<T> grad, Operand<? extends TNumber> indices, Options... options)
Factory method to create a class wrapping a new ResourceSparseApplyRmsProp operation.
Parameters
scope | current scope |
---|---|
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. |
grad | The gradient. |
indices | A vector of indices into the first dimension of var, ms and mom. |
options | carries optional attributes values |
Returns
- a new instance of ResourceSparseApplyRmsProp
public static ResourceSparseApplyRmsProp.Options useLocking (Boolean useLocking)
Parameters
useLocking | 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. |
