Kristoffer Wickstrøm
Stillingsbeskrivelse
Jeg er førsteamanuensis i Maskinlæringsgruppa ved UiT Norges arktiske universitet og forskningsleder for tolkbarhet i SFI Visual Intelligence. Mitt hovedforskningsområde er dyp læring, med særlig fokus på forklarbarhet og læring med begrensede data. Jeg er også interessert i usikkerhetsmodellering, informasjonsteori, kjernemetoder og medisinsk bildeanalyse. Jeg har tidligere vært gjesteforsker i bildebehandlingslaboratoriet ved Universitetet i Valencia med professor Gustau Camps-Valls og i Understandable Machine Intelligence Laboratory ved Technical University of Berlin med professor Marina M.-C. Höhne.
