Data Science and Artificial Intelligence have become the driving force of many businesses and are an integral part of our daily lives. Small and important decisions or the control of technical processes are based on knowledge gained from collected data. Advice from data driven analytics is integrated into business decisions and is the base of many new business models. Research in Data Science is progressing rapidly, more and more companies have successfully applied Data Science and Artificial Intelligence in countless scenarios. To account for the close interaction between science and application, the International Data Science Conference brings together researchers, scientists, engineers and entrepreneurs. The 3rd iDSC organized by FH Vorarlberg under the patronage of the Salzburg University of Applied Sciences has given an insight into state-of-the art research topics as well as best practice applications from industries and businesses. New approaches in the fields of machine learning, artificial intelligence, data mining and visualization as well as first-hand experience, best practice examples and novel applications from companies have been discussed.The proceedings include all full papers presented in the scientific track and the short papers from the industry track.EditorsPeter Haber is a Professor of Information and Communication Technology, in particular for analog and digital signal processing, and responsible coordinator for system theory and electrical engineering at Salzburg University of Applied Sciences.
