Update '*var' according to the momentum scheme.
tf.raw_ops.ResourceApplyKerasMomentum( var, accum, lr, grad, momentum, use_locking=False, use_nesterov=False, name=None )
Set use_nesterov = True if you want to use Nesterov momentum.
accum = accum * momentum - lr * grad var += accum
Args | |
---|---|
var | A Tensor of type resource . Should be from a Variable(). |
accum | 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. |
grad | A Tensor . Must have the same type as lr . The gradient. |
momentum | A Tensor . Must have the same type as lr . Momentum. 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. |
use_nesterov | An optional bool . Defaults to False . If True , the tensor passed to compute grad will be var + momentum * accum, so in the end, the var you get is actually var + momentum * accum. |
name | A name for the operation (optional). |
Returns | |
---|---|
The created Operation. |
