Artificial intelligence (AI) offers great potential for science and is one of the key technologies of the future. As a branch of computer science, AI deals with the development of intelligent systems to solve complex problems. In order to acquire the necessary skills in this field, the Leibniz Institute of Surface Engineering e.V. (IOM) organised the "AI School 2023" together with experts from the Center for Scalable Data Analytics and Artificial Intelligence (ScaDS.AI Dresden/Leipzig), which took place at the IOM in Leipzig from 16 to 20 October 2023. The participation free of charge for members of the Leibniz Association was facilitated by the Leibniz Research Network Mathematical Modelling and Simulation MMS. Additionally, the ScaDS.AI Dresden/Leipzig is supported by the BMBF and SMWK. 40 participants had the opportunity to learn the basics of machine learning (ML), gain practical experience in using common tools and to talk about their own problems with an expert from ScaDA.AI Dresden/Leipzig. The lectures covered a wide range of topics, from the basics of AI/ML to data visualisation and working on a high-performance cluster (HPC). In addition, the participants had the opportunity to exchange ideas and make contacts on the sidelines of the five-day event.
