Bug#240200: RFP: snob-vanilla -- MML-based automatic clustering; unsupervised learning



Package: wnpp
Severity: wishlist

* Package name    : snob-vanilla
  Version         : x.y.z

  Description     : MML-based automatic clustering; unsupervised learning
  Snob is a program for clustering, that is, for discovering the
  natural classes in data, without supervision. It is comparable to
  AutoClass (also available as a .deb), especially now that newer
  versions of AutoClass have started to mimic the Minimum Message
  Length induction in Snob. Minimum Message Length induction is a
  scale-invariant Bayesian technique based on information theory.
  In a paper by Upald and Neufeld (1996)
  comparing the unsupervised classifiers Snob, AutoClass, and ART2,
  Snob did the best and ART2 the worst, with AutoClass in the middle.
  Snob also used to have more powerful heuristics than AutoClass, but
  recent versions of AutoClass may have borrowed some of Snob's
  heuristics. This (vanilla) version of snob can handle
  both continuous and discrete (multistate) variables, but restricts
  continuous variables to Gaussian distributions. (Non-free versions
  of Snob can handle Poisson, von Mises, and other distributions.) In
  addition, the vanilla version assumes all variables are
  uncorrelated.  Snob has been applied to phenotypic taxonomy,
  bioinformatics, image compression, author identification,
  clinical psychology, and many other problems. For more

Snob-Vanilla is the GPL version of Snob. Chris Wallace is the author of 
this and most other versions of Snob. He has released this GPL. I have 
put it into CVS, made a better Makefile, upgraded the 
documentation, and created a .deb which works well enough here. I would 
like to include Snob-Vanilla in the official Debian distribution, but 
lack the packaging skill to take on that responsibility. I would be 
happy to work with someone who has the skill. 

I would be willing to pay moderate amounts for this service.
