python-cluster release 1.1.2

Michel Albert — Mon, 11 Mar 2013 13:05:08 -0000

Fixed bug caused by numpy arrays and KMeansClustering.

The KCuster constructor now accepts an optional function to test for item equality. If the clusters contain numpy arrays, you can pass "numpy.array_equals".

Project moved to github

Michel Albert — Mon, 11 Mar 2013 13:03:34 -0000

The project is now available in github here:
http://www.github.com/exhuma/python-cluster

The news-feed and project page will remain on sourceforge for now.

Migrated to SVN

Michel Albert — Sun, 14 Oct 2007 10:18:56 -0000

Finally migrated to SVN (https://sourceforge.net/svn/?group_id=170665).

I did not bother about migrating the history as well. Not really necessary for such a small project. I will leave CVS access enabled for a while but will take it down eventually. So if you pull from CVS, make sure that you switch to the SVN repo as soon as possible.

Broken Link

A helpful hand discovered a broken link in the source.

Broken link: http://mail.python.org/pipermail/python-list/2004-December/253517.html

Alternative link: http://mail.python.org/pipermail/python-list/2004-December/294990.html

It's not the same link, but contains similar information. I hope this link will stay.

python-cluster release 1.1.0b1

K-Means clustering is now implemented

python-cluster release 1.0.1b3

Michel Albert — Thu, 06 Jul 2006 11:42:31 -0000

This is a bug-fix release!
It fixes bug #1516204 that caused the clustering algorithm to raise an exception if an empty list or a list of only one item was supplied as argument.

In addition I added some unit-tests. This keeps development and bug-tracking a lot easier.

Typo. Not "ngram" but "cluster"

Michel Albert — Wed, 05 Jul 2006 06:49:45 -0000

Eeeks. The last header in the news read "new release for python-ngram". Although that is somewhat true, it really should have read "python-cluster".

Sorry.

Release of python-ngram 1.0.1b2

Michel Albert — Wed, 05 Jul 2006 06:47:54 -0000

Finally I got around to build the dist-files and upload them. Enjoy.

You might notice that there are only the source distribution and the windows binary distribution. I decided to drop the rest because they are in my opinion unneeded. They all behave exactly the same as the source distribution anyway. Yes, I could have created the other files as well for convenience, but how hard is it really to type "python setup.py install"? ;)

And yes, as the windows-people like the click-and-play behaviour, I kept the .exe file.

The other reason behind this, is that it's awkward to release multiple files on sourceforge. For *every* ... *single* ... *file* you have to select the settings and refresh the page. After the first few releases, it really becomes tedious and repetitive.

- End.

New version in CVS (1.0.1b2)

Michel Albert — Mon, 03 Jul 2006 16:51:07 -0000

I finished a new version today. Now the hierarchical clustering works twice(!) as fast. This is achieved because the distance-matrix which is generated internally is symmetric. So I only need to calculate one half of the possible combinations.

More improvement is possible. But I gave up on that today. Too complex.

I also started to work out the details for a K-Means algorithm on the Airport this weekend. On paper it looks sensible and I beleive it should work as I wrote it down. Now I only need to beam my scribblings onto the harddisk. And hope it all works ;)
