tensorflow::ops::ResourceSparseApplyKerasMomentum
#include <training_ops.h>
Update relevant entries in '*var' and '*accum' according to the momentum scheme.
Summary
Set use_nesterov = True if you want to use Nesterov momentum.
That is for rows we have grad for, we update var and accum as follows:
accum = accum * momentum - lr * grad var += accum
Arguments:
- scope: A Scope object
- var: Should be from a Variable().
- accum: Should be from a Variable().
- lr: Learning rate. Must be a scalar.
- grad: The gradient.
- indices: A vector of indices into the first dimension of var and accum.
- momentum: Momentum. Must be a scalar.
Optional attributes (see Attrs
):
- use_locking: 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: 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.
Returns:
- the created
