Possible readings and topics
(Bozena) Alon (2009) - How To Choose a Good Scientific Problem Alon_2009.pdf
- (Alex) hierarchical Bayesian models (what is a chinese restaurant process? what is an indian buffet?). This could (should) stay at a conceptual level, and address questions like
- what kinds of problems do these approaches lend themselves to?
- for these problems, what kinds of theoretical or computational approaches were people taking before these hierarchical models existed?
- similarly, what are the alternatives/objections to these models nowadays?
- how are hierarchical bayesian models related to/different from multi-level regression?
- (Alex) what do people really mean when they say "learning"? (maybe dick could be consulted about this?)
- what is the difference between supervised and unsupervised learning?
- what sub-types of learning exist within these categories?
- large parts of the field seem to have essentially forgotten about "classical" approaches to learning (associative learning, conditioning, etc.)
- (Alex) Dry run for CUNY talk? maybe me and chigusa on the same day.
- (Bozena) For later in the semester (perhaps mid/late March or so) I would be interested in presenting some modeling work I've been doing.
(Bozena) If we have a meeting on the general topic of how to get organized, I could talk about the software I'm using, OmniFocus, which implements David Allen's "Getting things done" philosophy. I could talk a bit about the general philosophy, and then show how the software works. It'd probably take about 15-20 minutes
- (Dan) I think tutorials about stats and modeling would be most useful for me. I would also be interested in learning about study design constraints/rules with methodologies that I have yet to use (self paced reading) and definitely corpus analysis tutorials.
(Chigusa) I would be interested in reading some papers on assumptions about sampling in learning (like Xu and Tenenbaum and also the following paper) SAMPLING ASSUMPTIONS IN LANGUAGE LEARNING Anne Hsu and Thomas Griffiths (submitted)
