The UNH AI group meets weekly to discuss on-going work and interesting papers from the literature.  Please bring your own copy of any paper under discussion. If you are new to this kind of thing, you might want to read How to Read a Paper.  We'll probably be in Kingsbury N233 unless otherwise noted.  As always, watch the AI group mailing list for details.

 

Some ideas for future readings are on the Suggested Reading page.

 

Summer, 2026

We meet Tuesdays and alternate Thursdays 10-11am in Kingsbury N233 and on teams (let Wheeler know if you need to be remote).  Please monitor the mailing list and teams for late-breaking announcements!
