Class ResourceApplyAdadelta

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.ResourceApplyAdadelta

All Implemented Interfaces:

Op

@Operator
public final class ResourceApplyAdadelta
extends PrimitiveOp

Update '*var' according to the adadelta scheme.

accum = rho() * accum + (1 - rho()) * grad.square(); update = (update_accum + epsilon).sqrt() * (accum + epsilon()).rsqrt() * grad; update_accum = rho() * update_accum + (1 - rho()) * update.square(); var -= update;

Method Detail

create

public static <T> ResourceApplyAdadelta create(Scope scope,
                                               Operand<?> var,

                                               ResourceApplyAdadelta.Options... options)

Factory method to create a class to wrap a new ResourceApplyAdadelta operation to the graph.

Parameters:

scope - current graph scope

var - Should be from a Variable().

accum - Should be from a Variable().

accumUpdate - Should be from a Variable().

lr - Scaling factor. Must be a scalar.

rho - Decay factor. Must be a scalar.

epsilon - Constant factor. Must be a scalar.

grad - The gradient.

options - carries optional attributes values

Returns:

a new instance of ResourceApplyAdadelta

useLocking

public static ResourceApplyAdadelta.Options useLocking(Boolean useLocking)

Parameters:

useLocking - If True, updating of the var, accum and update_accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
