The AI Day at Dipoli on 13 December 2017. The sold-out event, or- ganised by FCAI, gathered over 600 people to Otaniemi. Representa- tives of over 180 companies joined academics and public-sector par- ticipants to hear keynote speeches from top AI researchers and to benefit from the matchmaking opportunities during pitching, demo and poster sessions.
