ScatterMax
#include <state_ops.h>
Reduces sparse updates into a variable reference using the
max
operation.
Summary
This operation computes
# Scalar indices ref[indices, ...] = max(ref[indices, ...], updates[...]) # Vector indices (for each i) ref[indices[i], ...] = max(ref[indices[i], ...], updates[i, ...]) # High rank indices (for each i, ..., j) ref[indices[i, ..., j], ...] = max(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 contributions combine.
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 reduce into
ref
.
Optional attributes (see
Attrs
):
- use_locking: If True, the update will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
Returns:
-
Output
: = Same asref
. Returned as a convenience for operations that want to use the updated values after the update is done.
