public final class
ResourceApplyKerasMomentum
Update '*var' according to the momentum scheme.
Set use_nesterov = True if you want to use Nesterov momentum.
accum = accum * momentum - lr * grad var += accum

Public Methods
public static ResourceApplyKerasMomentum create (Scope scope, Operand<?> var, Operand<?> accum, Operand<T> lr, Operand<T> grad, Operand<T> momentum, Options... options)
Factory method to create a class wrapping a new ResourceApplyKerasMomentum operation.
Parameters
scope | current scope |
---|---|
var | Should be from a Variable(). |
accum | Should be from a Variable(). |
lr | Scaling factor. Must be a scalar. |
grad | The gradient. |
momentum | Momentum. Must be a scalar. |
options | carries optional attributes values |
Returns
- a new instance of ResourceApplyKerasMomentum
public static ResourceApplyKerasMomentum.Options useLocking (Boolean useLocking)
Parameters
useLocking | 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. |
---|
public static ResourceApplyKerasMomentum.Options useNesterov (Boolean useNesterov)
Parameters
useNesterov | 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. |
