cave.utils.convert_for_epm module

cave.utils.convert_for_epm.convert_data_for_epm(scenario: smac.scenario.scenario.Scenario, runhistory: smac.runhistory.runhistory.RunHistory, impute_inactive_parameters=False, rng=None, logger=None)

converts data from runhistory into EPM format

Parameters

• scenario (Scenario) – smac.scenario.scenario.Scenario Object

• runhistory (RunHistory) – smac.runhistory.runhistory.RunHistory Object with all necessary data

• impute_inactive_parameters (bool) – whether to impute all inactive parameters in all configurations - this is needed for random forests, as they do not accept nan-values

Returns

• X (np.array) – X matrix with configuartion x features for all observed samples

• y (np.array) – y matrix with all observations

• types (np.array) – types of X cols – necessary to train our RF implementation
