SparseApplyRmsProp

public final class SparseApplyRmsProp

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 Output<T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static SparseApplyRmsProp<T> create (Scope scope, Operand<T> var, Operand<T> ms, Operand<T> 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 SparseApplyRmsProp 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 SparseApplyRmsProp

public Output<T> out ()

Same as "var".

public static SparseApplyRmsProp.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.
