Chicago Machine Learning Meetup

  • Apr 4, 2012 · 5:30 PM
  • This location is shown only to members

This meeting will be a special interactive "study group" session of the Machine Learning Group.  The topic is "Semi Supervised Learning Over Text" as presented by Dr. Tom Mitchell, Chair of the Machine Learning Department of Carnegie Mellon University. Please try to view the lecture ahead of time, it's free to view and includes downloadable slides. We'll discuss the lecture at the meeting, but won't show it again due to its length.

1 hour video:

Downloadable Slides:

Topics covered in the presentation are "bag of words" Naive Bayes classification, an "EM step" enhancement to Naive Bayes, and finally co-training with redundantly predictive features.

Rob Reinhold, a long-time employee of Orbitz but new to Machine Learning, will be leading a discussion about the presentation and related topics. Think of this as time to share your thoughts and what you learned from the presentation, ask your peers questions about anything you had trouble with and - most importantly - enjoy free pizza and beer on a Wednesday.

    This was a great event. I was skeptical at first; it was my first meetup, and the first with the group. The discussion was great, and thought-provoking--I watched the video beforehand, and sort-of understood it; but the discussion highlighted some points toward the end of the video that make more sense to me now.

    I prefer the old format because the presentations seemed to cover topics not easily found in a textbook or on the web. But I'm OK with the new format. Perhaps we could dive into some of the topics Andrew Ng covered in last semester's ML online Stanford course:

    I want to thank Rob Lancaster for making all this happen. Good job man!

    This time meeting was setup as a study group. There was a facilitator going over the power point slides (sent earlier via email to to registered participants) of renowned professor Tom Mitchell. Audience were the participants in discussion. It was highly effective learning in a non-threatening environment. I always find this meetup group friendly, easy going and highly educational. There was no pressure for you to speak but on the other hand everybody had equal opportunity to speak if they want to.

    Good population of Techronin and more conventional knowledge professionals. Would be nice to maybe have more specific events with time periods for networking, small group based problem hacking and things like that. But definitely a really solid event! Looking forward to the Hackathon.

    I learned a lot. More study groups would be cool.

    I thought this format worked great: it fostered a lot of discussion and worked well with a group of mixed levels of experience with ML.

    Rob R. did a great job leading us through the material and leading the discussion. The material was well-chosen for its interesting-ness, accessibility, and brevity.
