#include <state_ops.h>
Subtracts sparse updates to a variable reference.
```python 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:]
.
Arguments:
Variable
node.ref
.ref
.Optional attributes (see Attrs
):
Returns:
Output
: = Same as ref
. Returned as a convenience for operations that want to use the updated values after the update is done. Constructors and Destructors | |
