Despite great successes in many fields, machine learning typically requires substantial human resources to determine a good machine learning pipeline (including various types of preprocessing, and the choice of classifiers and hyperparameters). AutoML aims to free human practitioners and researchers from these menial tasks. The current state-of-the-art in AutoML has been evaluated in the AutoML challenge 2018. Here, we describe our winning entry to this challenge, dubbed PoSH Auto-sklearn, which combines an automatically preselected portfolio, ensemble building and Bayesian optimization with successive halving. Finally, we share insights in the importance of different parts of our approach
