Hello, I’m Marko Horvat. I’m a computer scientist and assistant professor affiliated with Zagreb University of Applied Sciences (TVZ), University of Zadar and University of ZagrebFaculty of Electrical Engineering and Computing (FER) in Croatia.

I hold a PhD in Computer Science from University of Zagreb, Faculty of Electrical Engineering and Computing. I’m the head of the Artificial Intelligence Laboratory at Zagreb University of Applied Sciences (TVZ AI Lab) and active participant in several research projects focused on data mining of EEG time series data, linking semantic and affective knowledge, prediction of emotion, stress and fatigue using pervasive hardware, and development of multimedia stimuli databases with tools for their construction and multifaceted retrieval.

This site showcases some of the research I’ve done, including my CV and software tools which can be freely downloaded for academic purposes and a blog on topics that intersect affective computing, machine learning, knowledge representation and information retrieval. 

Research keywords: machine learning, automated reasoning, formal knowledge representation, affective computing, linked data and the semantic web
