Where can I find 'no limits' Texas Hold'em game logs?
Building a Poker Playing Agent based on Game Logs using Supervised Learning

I found this paper on creating a Hold'em AI that refers to two external log files on page 100 of that paper. One no longer exists. The other, from hhsmithy, costs a couple bucks. They offer logs from various sources, including Poker Stars, Full Tilt Poker and Party Poker.

They also offer a smaller, free set that you can use to build your setup.
