DAGStat Conference 2022

Talklets

In view of the limited number of on site talks, we provide talklets of participants who cannot give a live talk (selected among the initial submissions). Three prizes will be awarded for the best talklets. A jury will watch and evaluate the talklets in advance. The winners will be announced during the plenary lecture on Thursday (5:00 pm) and the prizes will be sent to the winners afterwards if they participate online.

All video files are accessible for the conference participants via the video platform

of the UHH. Please find below the links to the talklets sorted by session.
