I work on personalized AI that can assist users in line with their own intentions and preferences. Recently, I am especially interested in flexible, general-purpose user modeling that can be transferred across a variety of computational aesthetics tasks, achieved by capturing users' essential aesthetic values toward photographs and artworks.
