ResourceApplyAdadelta

public final class ResourceApplyAdadelta

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;

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "ResourceApplyAdadelta"

Public Methods

public static ResourceApplyAdadelta create (Scope scope, Operand<?> var, Operand<?> accum, Operand<?> accumUpdate, Operand<T> lr, Operand<T> rho, Operand<T> epsilon, Operand<T> grad, Options... options)

Factory method to create a class wrapping a new ResourceApplyAdadelta operation.

Parameters
scope current 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

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.
