tf.raw_ops.ResourceApplyPowerSign(
var, m, lr, logbase, sign_decay, beta, grad, use_locking=False, name=None
)
m_t <- beta1 * m_{t-1} + (1 - beta1) * g update <- exp(logbase * sign_decay * sign(g) * sign(m_t)) * g variable <- variable - lr_t * update
| Args | |
|---|---|
| var | A Tensor of type resource. Should be from a Variable(). |
| m | 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. |
| logbase | A Tensor. Must have the same type as lr. Must be a scalar. |
| sign_decay | A Tensor. Must have the same type as lr. Must be a scalar. |
| beta | A Tensor. Must have the same type as lr. 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 and m tensors is 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. |
