tensorflow::ops::ScatterSub

#include <state_ops.h>

Subtracts sparse updates to a variable reference.

Summary

    # Scalar indices
    ref[indices, ...] -= updates[...]
 

    # Vector indices (for each i)
    ref[indices[i], ...] -= updates[i, ...]
 

    # High rank indices (for each i, ..., j)
    ref[indices[i, ..., j], ...] -= updates[i, ..., j, ...]

This operation outputs ref after the update is done. This makes it easier to chain operations that need to use the reset value.

Duplicate entries are handled correctly: if multiple indices reference the same location, their (negated) contributions add.

Requires updates.shape = indices.shape + ref.shape[1:] or updates.shape = [].

Args:

  • scope: A Scope object
  • ref: Should be from a Variable node.
  • indices: A tensor of indices into the first dimension of ref.
  • updates: A tensor of updated values to subtract from ref.

Optional attributes (see Attrs):

  • use_locking: If True, the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

Returns:

  • Output: = Same as ref. Returned as a convenience for operations that want to use the updated values after the update is done.
