Heri Ramampiaro
About
Ramampiaro is Head of department and Professor at the Department of Computer Science, NTNU Trondheim. He has previously been Head of the Data and Artificial Intelligence (DART) group. Ramampiaro has been central in the establishment of the Telenor–NTNU AI-Lab, an AI research center at NTNU (now Norwegian Open AI-Lab), for which he was NTNU's scientific coordinator. His current main research interests include information retrieval, information extraction, data/text mining and machine learning.
He has been leader for the Norwegian goverment's expert group on sharing of industrial data (2021-2022). More information about this work can be found here and here (in Norwegian).
