Bases:
FedAvg
可配置的 QFedAvg 策略实施。
Methods
aggregate_evaluate
(server_round, results, ...)采用加权平均法计算评估损失总额。
aggregate_fit
(server_round, results, failures)使用加权平均法汇总拟合结果。
configure_evaluate
(server_round, parameters, ...)配置下一轮评估。
configure_fit
(server_round, parameters, ...)配置下一轮训练。
evaluate
(server_round, parameters)使用评估函数评估模型参数。
initialize_parameters
(client_manager)初始化全局模型参数。
num_evaluation_clients
(num_available_clients)使用部分可用客户进行评估。
num_fit_clients
(num_available_clients)返回样本大小和所需的可用客户数量。
