tensorflow::ops::SparseApplyAdagrad

#include <training_ops.h>

Update relevant entries in '*var' and '*accum' according to the adagrad scheme.

Summary

That is for rows we have grad for, we update var and accum as follows:

$$accum += grad * grad$$
$$var -= lr * grad * (1 / sqrt(accum))$$

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.

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.

Returns:
