Creates a TFF computation that aggregates metrics via sum_then_finalize
.
tff.learning.metrics.sum_then_finalize(
metric_finalizers: Union[tff.learning.metrics.MetricFinalizersType
, tff.learning.metrics.FunctionalMetricFinalizersType
],
local_unfinalized_metrics_type: Optional[tff.types.StructWithPythonType
] = None
) -> tff.Computation
The returned federated TFF computation is a polymorphic computation that
accepts unfinalized client metrics, and returns finalized, summed metrics
placed at the server. Invoking the polymorphic computation will initiate
tracing on the argument and will raise a ValueError
if the keys (i.e.,
metric names) in metric_finalizers
are not the same as those of the argument
the polymorphic method is invoked on.
Note: invoking this computation outside of a federated context (a method
decorated with tff.federated_computation
) will require first wrapping it in
a concrete, non-polymorphic tff.Computation
with appropriate federated
types.
Returns
A federated TFF computation that sums the unfinalized metrics from
CLIENTS
, and applies the correponding finalizers at SERVER
.
Raises
TypeError
If the inputs are of the wrong types.
