Update '*var' according to the adadelta scheme.

    var,
    accum,
    accum_update,
    lr,
    rho,
    epsilon,
    grad,
    use_locking=False,
    name=None
)
accum = rho() * accum + (1 - rho()) * grad.square();

| Args | 
|---|
| var | A Tensorof typeresource. Should be from a Variable(). | 
| accum | A Tensorof typeresource. Should be from a Variable(). | 
| accum_update | A Tensorof typeresource. 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,uint16,complex128,half,uint32,uint64.
Scaling factor. Must be a scalar. | 
| rho | A Tensor. Must have the same type aslr.
Decay factor. Must be a scalar. | 
| epsilon | A Tensor. Must have the same type aslr.
Constant factor. Must be a scalar. | 
| grad | A Tensor. Must have the same type aslr. The gradient. | 
| use_locking | An optional bool. Defaults toFalse.
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). | 
| Returns | 
|---|
| The created Operation. |
