tensorflow:: ops:: ResourceSparseApplyMomentum

#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 + grad var -= lr * accum

Args:

  • 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 - lr * momentum * accum, so in the end, the var you get is actually var - lr * momentum * accum.
