| ## Args ||
|---|---|
| `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`, `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). |
