var A Tensor of type resource. Should be from a Variable().
accum A Tensor of type resource. Should be from a Variable().
linear A Tensor of type resource. Should be from a Variable().
grad 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. The gradient.
lr A Tensor. Must have the same type as grad. Scaling factor. Must be a scalar.
l1 A Tensor. Must have the same type as grad. L1 regularization. Must be a scalar.
l2 A Tensor. Must have the same type as grad. L2 shrinkage regularization. Must be a scalar.
l2_shrinkage A Tensor. Must have the same type as grad.
lr_power A Tensor. Must have the same type as grad. Scaling factor. Must be a scalar.
use_locking An optional bool. Defaults to False. If True, updating of the var and accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
multiply_linear_by_lr An optional bool. Defaults to False.
name A name for the operation (optional).

The created Operation.
