Konstantinos Bougiatiotis

I am a Ph.D. candidate in Computer Science and my primary focus is data science and machine learning. I hold a research associate position with the Institute of Informatics and Telecommunications of the National Center for Scientific Research “Demokritos”, where I am involved with several international projects.

I am part of the Document Intelligence Center of Excellence and I conduct research under the guidance of Dr. George Paliouras.
