tff.framework.FederatedComposingStrategy

A strategy for composing federated types and intrinsics in disjoint scopes.

Inherits From: FederatingStrategy

tff.framework.FederatedComposingStrategy(
    executor: tff.framework.FederatingExecutor,
    server_executor: tff.framework.Executor,
    target_executors: List[tff.framework.Executor],
    local_computation_factory: local_computation_factory_base.LocalComputationFactory = tensorflow_computation_factory.TensorFlowComputationFactory()
)

This strategy implements the FederatingStrategy interface and provides logic for handling federated types and federated intrinsics on an underlying collection of target executors. This strategy can be used in hierarchical aggregation structures with federating executors handling disjoint scopes at the leafs.

This strategy only supports the placements:

executor A federating_executor.FederatingExecutor to use to handle unplaced types, computations, and processing.
server_executor The parent executor to use for all processing at the parent, such as combining values from child executors, unplaced and server-side processing, etc.
target_executors The list of executors that manage disjoint scopes to combine in this executor, delegate to and collect or aggregate from.
local_computation_factory An instance of LocalComputationFactory to use to construct local computations used as parameters in certain federated operators (such as tff.federated_sum, etc.). Defaults to a TensorFlow computation factory that generates TensorFlow code.

TypeError If server_executor is not an executor_base.Executor or if target_executors is not a list of executor_base.Executors.
