flat_survey_integrator module

class FlatSurveySamplingIntegrator(*args, **kwargs)[source]

Bases: zunis.integration.flat_survey_integrator.PosteriorSurveySamplingIntegrator

Parameters

  • f (function) – the function to integrate

  • n_iter (int) – general number of iterations - ignored for survey/refine if n_iter_survey/n_inter_refine is set

  • n_iter_survey (int) – number of iterations for the survey stage

  • n_iter_refine (int) – number of iterations for the refine stage

  • n_points – general number of points per iteration - ignored for survey/refine if n_points_survey/n_points_refine is set

  • n_points_survey (int) – number of points per iteration for the survey stage

  • n_points_refine (int) – number of points per iteration for the refine stage

  • use_survey (bool) – whether to use the points generated during the survey to compute the final integral not recommended due to uncontrolled correlations in error estimates

  • verbosity (int) – verbosity level of the integrator

class PosteriorSurveySamplingIntegrator(*args, **kwargs)[source]

Bases: zunis.integration.base_integrator.BaseIntegrator

Integrator using a target space posterior to sample during survey: Takes a trainer object at initialization and samples from a given distribution in target space during the survey phase. The function to integrate is given at initialization.

Parameters

  • f (function) – the function to integrate

  • n_iter (int) – general number of iterations - ignored for survey/refine if n_iter_survey/n_inter_refine is set

  • n_iter_survey (int) – number of iterations for the survey stage

  • n_iter_refine (int) – number of iterations for the refine stage

  • n_points – general number of points per iteration - ignored for survey/refine if n_points_survey/n_points_refine is set

  • n_points_survey (int) – number of points per iteration for the survey stage

  • n_points_refine (int) – number of points per iteration for the refine stage

  • use_survey (bool) – whether to use the points generated during the survey to compute the final integral not recommended due to uncontrolled correlations in error estimates

  • verbosity (int) – verbosity level of the integrator
