Population

API reference: pe.population package.

pe.population.Population is responsible for generating the initial synthetic samples and the new synthetic samples for each Private Evolution iteration. It has the following key methods:

• pe.population.Population.initial(): Generates the initial synthetic samples.

• pe.population.Population.next(): Generates the synthetic samples for the next Private Evolution iteration.

Available Populations

• pe.population.PEPopulation is the default implementation of pe.population.Population. It supports the key population algorithms from existing Private Evolution papers (https://github.com/fjxmlzn/private-evolution-papers).

• pe.population.CompositePopulation, proposed in Tab-PE, can be used when different Private Evolution iterations should use different population algorithms or settings. It takes a list of pe.population.Population objects, uses the first population to generate the initial synthetic samples, and then uses the population at each iteration index to generate the next synthetic samples. This is useful for combining multiple population strategies within a single Private Evolution run.
