The UNH AI group meets weekly to discuss on-going work and interesting papers from the literature.  (This is in addition to any graduate AI seminar that might be occurring, although those in the seminar are excused from reading the papers for the research group meetings.)  Please bring your own printed copy of any paper or handout. 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 and calendar for details.

 

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

Summer, 2025

We will meet Tuesdays and Thursdays 10:30-11:30am in N233 (or email Wheeler for a zoom link).  Please monitor the mailing list and teams for late-breaking announcements!
