This is just a few quick few notes about the events at AAAI this year and my own biased view of what was hot. But keep in mind there is such a broad set of papers, presentations, posters and demos from a huge number of brilliant people that its impossible for one person to give you a full view of what went on. I encourage you to look over the program here, and read the papers that interest you.
From the conference talks I attended and the people I talked to people were most excited about:
- Learning Relationships from Social Networks - lots of fascinating work here including one of the invited talks. Kind of ironic though that so few AAAI11 attendees seem to use social media like twitter during the conference. You can take a look at #aaa11 (and even #aaai and #aaai2011) for the limited chatter there was.
- Planning with UCT and bandit problems
- Microtext (I don't know what that is but it's apparently fascinating)
- Computational Social Choice - a Borda manipulation proof won outstanding paper in this track.
- Multiagent Systems applied to everything
- Computational Sustainability
- Natural Language Processing - especially from blogs and social media
- and everyone I talked to seems to agree that Watson was pretty awesome
The poster session was very full and lots of great discussion ensued. Note for future attendees, best food of the conference was at the posters, by far, go for the food, stay for the Artificial Intelligence.
There were a number of robot demos as well, the fantastic PR2 platform was being demonstrated with an algorithm where users could train it to identify and manipulate household items like dishes and cups. There were also a number of chess playing robots playing in competition, designed to be played against a human using vision to detect moves and locate pieces.
There was also a lot else going on I didn't get to: The AI in Education track, a poker playing competition, IAAI the applied AI conference held in parrallel with AAAI and probably lots more.
To top it off, on Thursday morning those of us staying in the hotel were awakened to bull horns and shouted slogans. I had almost hoped that someone had arranged a protest spawned by the frightening advance of Artificial Intelligence and they had come to demand we stop our research immediately to avoid the inevitable enslavement/destruction/unemployment/ingestion of humanity by the machines. Not that this would be a valid concern or that I want to stop researching, but it would have provided some kind of strange vindication that the public thinks we are advancing.
Unfortunately it was actually a labour dispute between the Hyatt and some of its staff, they marched in front of the main entrance from 7am-7pm the entire final day of the conference.
Best overheard quote:
You care about AI more than our jobs!
I'm pretty sure most attendees didn't have a predefined utility for comparing those two entities. Hopefully they work it out.
All in all, a great conference in a great city.
