We would like to welcome you to the «3rd COST Conference on Mathematics for Industry in Switzerland» on Artificial Intelligence in Industry and Finance, hosted by the Institute of Applied Mathematics and Physics and the Institute of Data Analysis and Process Design at the Zurich University of Applied Sciences ZHAW in Winterthur, Switzerland. The aim of this conference is to bring together European academics, young researchers, students and industrial practitioners to discuss the application of Artificial Intelligence in Industry and Finance within the COST research network. This conference is supported by COST Action TD1409, Mathematics for Industry Network (MI-NET) and by the Swiss State Secretariat for Education, Research and Innovation SERI. COST is the longest-running European framework supporting transnational cooperation among researchers, engineers and scholars across Europe. The 1st COST Conference on this topic was held on September 15, 2016, and the 2nd COST Conference was held on September 7, 2017. Scientific topics Artificial Intelligence challenges for European companies from the mechanical and electrical industry, but also life sciences. Artificial Intelligence challenges for the European Fintech industry, banks and insurance companies. Speakers We have invited a large number of speakers both from within Switzerland as well as abroad, working on AI in Finance and Industry. One track will focus on financial mathematics and its applications of machine learning, whereas the other one will tackle the implications for industry. In addition, we have a focus session on Fintech-Driven Automation in the Financial Industry.
