ResourceApplyRmsProp

public final class ResourceApplyRmsProp

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 ResourceApplyRmsProp create (Scope scope, Operand<?> var, Operand<?> ms, Operand<?> mom, Operand<T> lr, Operand<T> rho, Operand<T> momentum, Operand<T> epsilon, Operand<T> grad, Options... options)

Factory method to create a class wrapping a new ResourceApplyRmsProp 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.
options	carries optional attributes values

Returns

a new instance of ResourceApplyRmsProp

public static ResourceApplyRmsProp.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.
