Re: [Tutor] Cluster algorithms
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Are there any example programs depicting Clustering algorithms such as agglomerative, complete link, partional , squared error clustering, k-means or clustering algos based on Neural networks or genetic algorithm. although I just learned python, (to major extent in programming also), I need to apply some of these algos to my data. Any suggestions/recommendations? Have you looked at the orange machine learning tool kit, many clustering, classification and learning tools are implemented in this package. PLus it has a nice widget style interface now where you can build your own tools. (if you like to use widgets, or you can just write you own code calling it). Its all GPL and its pretty fantastic stuff. http://magix.fri.uni-lj.si/orange/ good luck kim Dr Kim Branson Diffraction and Theory CSIRO Health Sciences and Nutrition 343 Royal Parade, Parkville Melbourne Ph +613 9662 7136 [EMAIL PROTECTED] -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (Darwin) iD8DBQFB+P+Oer2hmGbHcokRApb0AJ91FNkREGPCawfRFQqP4/HcDp+QEACfTSTO VxKX/E3bY/Y8WKCHOM+ydQU= =fEya -END PGP SIGNATURE- ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

You can see the article at http://www.kuro5hin.org/story/2003/11/11/17383/475 . Perceptrons probably aren't *useful* to you in sorting your data, but the code should provide some insight into how you can do classification in python. Python is excellent for data mining and classification, thanks to the excellent numarray module as well as the ipython shell and several visualization libraries. I use it in place of Maple, Mathematica, Matlab, or some other specialized mathematics package. > Do I have to know to code well using OOP methods to > apply these algorithms? > I call some methods on matrix objects in the tutorial, but don't use any OOP. In fact, I often find that strict OOP is not so useful for numerical algorithms, where your code will often have to be optimized for speed.
