Biography

Dr. Tomáš Horváth received his MSc and PhD degrees at the Pavol Jozef Šafárik University in Košice, Slovakia, in 2002 and 2008, respectively, in the area of relational learning. Since 2004, he is a the member of the faculty of the Institute of Computer Science of the Faculty of Science at this university. He was on a post-doc internship at the Information Systems and Machine Learning lab of the University in Hildesheim, Germany, from 2009 to 2012 where he was working in the area of recommender systems with applications in education. From 2015 to 2016 he received a post-doc grant at the Department of Computer Science, University of São Paulo in São Carlos, Brazil, where he started to work on automated machine learning with focus on hyper-parameter learning. From 2016 until 2024, he was working as an associate professor at the Faculty of Informatics at the Eötvös Loránd University in Budapest, Hungary where he built the Department of Data Science and Engineering of which he was the head of for more than 6 years. He was continuing to work on automated working on automated machine learning and started to work on applied machine learning for the agriculture domain. From 2024 he is a professor of artificial intelligence at the Edinburgh Napier University, Scotland, UK.

His research interests include relational and rule-based learning, pattern mining, recommender systems, automated machine learning and precision farming.
