fl4health.client_managers.poisson_sampling_manager module

class PoissonSamplingClientManager

Bases: BaseFractionSamplingManager

Overrides the Simple Client Manager to Provide Poisson Sampling for Clients rather than fixed without replacement sampling

sample_fraction(sample_fraction, min_num_clients=None, criterion=None)

Poisson Sampling of Flower ClientProxy instances with a probability determine by sample_fraction.

Parameters:

• sample_fraction (float) – Fraction, which sets the Poisson sampling probability

• min_num_clients (int | None, optional) – minimum number of clients to be selected (overrides sampling to some extent). Defaults to None.

• criterion (Criterion | None, optional) – Criterion to sample clients based on. Defaults to None.

Returns:

List of selected ClientProxy objects represented the clients selected by the process.

Return type:

list[ClientProxy]
