FedXgbNnAvg¶

class FedXgbNnAvg(*args: Any, **kwargs: Any)[source]¶

Configurable FedXgbNnAvg strategy implementation.

Warning

This strategy is deprecated, but a copy of it is available in Flower Baselines: https://github.com/adap/flower/tree/main/baselines/hfedxgboost.

Methods

`aggregate_evaluate`(server_round, results, ...)	Aggregate evaluation losses using weighted average.
`aggregate_fit`(server_round, results, failures)	Aggregate fit results using weighted average.
`configure_evaluate`(server_round, parameters, ...)	Configure the next round of evaluation.
`configure_fit`(server_round, parameters, ...)	Configure the next round of training.
`evaluate`(server_round, parameters)	Evaluate model parameters using an evaluation function.
`initialize_parameters`(client_manager)	Initialize global model parameters.
`num_evaluation_clients`(num_available_clients)	Use a fraction of available clients for evaluation.
`num_fit_clients`(num_available_clients)	Return the sample size and the required number of available clients.
