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

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%.
