great resource!! what is it about NZ and machine learning :) (weka comes from there, for those who are not aware) Anyway, PyML (http://pyml.sourceforge.net/) and biopython (http://biopython.org) are two other packages I found pretty useful and can be explored..

You probably mean Weta Digital (http://www.wetafx.co.nz/), named after a New Zealand insect (http://en.wikipedia.org/wiki/Weta). Confusing matters is the fact that Weta Digital is located just off Weka Street (my old street, coincidentally), which is named after a New Zealand bird (http://en.wikipedia.org/wiki/Weka).

No, he means Weka: http://www.cs.waikato.ac.nz/ml/weka/

Ah. Thanks for the correction.

Pretty good code, and quite a bit of it. It's hardly a "repository", though, as it's just example code from the site's book. There is, however, a nice link down at the very bottom for machine learning data sets. Gotta save that one...

Taking into account that it's meant to go with the book, it's even decently commented. In quite a few of them, though, it'd be hard to puzzle out reasons for doing things without already knowing the logic.

Has anyone here read this book? Does it come recommended?

Same here, I'd be interested if anyone knows of a good machine learning / AI "cookbook" (to borrow O'Reilly book's metaphor), in Python.

You may try Programming Collective Intelligence if you haven't already (it's actually a O'Reilly book ;).
