Kurzfassung	PRIM (Patient Rule Induction Method) is an algorithm used for discovering scenarios, by creating hyperboxes in the input space. Yet PRIM alone usually requires large datasets and computational simulations can be expensive. Consequently, one wants to obtain scenarios while reducing the number of simulations. It has been shown, that combining PRIM with machine learning models, can reduce the number of necessary simulation runs by around 75%. In this thesis, I analyze nine different active learning sampling strategies together with several machine learning models, in order to find out if active learning can systematically improve PRIM even further, and if out of those strategies and models, a most beneficial combination of sampling method and intermediate machine learning model exists for this purpose.

-|kurzfassung=PRIM (Patient Rule Induction Method) is an algorithm for discovering scenarios from simulations, by creating hyperboxes, that are human-comprehensible. Yet PRIM alone requires relatively large datasets and computational simulations are usually quite expensive. Consequently, one wants to obtain a plausible scenario, with a minimal number of simulations. It has been shown, that combining PRIM with  ML models, which generalize faster, can reduce the number of necessary simulation runs by around 75%.
