In recent years, AI made impressive results in different applications possible, e.g., in computer vision, natural language processing or game playing. These breakthroughs show how AI will influence and change our daily lives in many fields. With the advent of deep learning and also traditional AI methods, such as AI planning, SAT solving or evolutionary algorithms, a multitude of different techniques are available these days. However, applying these techniques is challenging and even experienced AI developers are faced with several difficult design decisions, such as which algorithms to apply and how to set their corresponding hyperparameters. Unfortunately, the performance and thus the success of AI systems strongly depend on these small but important design decisions. To make AI easy-to-use for more users (even for those without a strong background in AI), we develop automated machine learning (AutoML) methods, which address many different research questions, such as: (i) how to predict the best algorithm for a given input? (ii) how to efficiently search for well-performing hyperparameter settings of an algorithm? (iii) how to efficiently analyze the performance of algorithms and their inputs? Finding solutions to such problems will lead to a democratization of AI which will unleash the true potential of AI.
