tf.raw_ops.ResourceApplyAdadelta

Update '*var' according to the adadelta scheme.

tf.raw_ops.ResourceApplyAdadelta(
    var,
    accum,
    accum_update,
    lr,
    rho,
    epsilon,
    grad,
    use_locking=False,
    name=None
)

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;

var A Tensor of type resource. Should be from a Variable().
accum A Tensor of type resource. Should be from a Variable().
accum_update A Tensor of type resource. Should be from a Variable().
lr A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, qint16, quint16, uint16, complex128, half, uint32, uint64. Scaling factor. Must be a scalar.
rho A Tensor. Must have the same type as lr. Decay factor. Must be a scalar.
epsilon A Tensor. Must have the same type as lr. Constant factor. Must be a scalar.
grad A Tensor. Must have the same type as lr. The gradient.
use_locking An optional bool. Defaults to False. 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.
name A name for the operation (optional).

The created Operation.
