A minor release for LIBSVM Plus is out, just to introduce an experimental support for compiling the code on Windows machine. The patch has been provided by Vladislavs Dovgalecs, from the Université Bordeaux I in France.
Please, refer to the “Windows” section within the README.plus file to know how to compile the library on Windows using Visual Studio.
Back on the 1st of November 2009, Chang and Lin released the version 2.9 of the well known LIBSVM library. A couple of months laster, I have finally found the time to backport the changes in my LIBSVM Plus, now at the 2.9 version as well.
The backport this time was very easy, because there were no major changes. Python tools have been updated as well, and now they should work with Python 3 too.
On the “Plus” side no changes have been made, except some tiny bug fixes. One note, that you will find also at the bottom of the LIBSVM Plus page, is that now LIBSVM Plus is hosted on Github too.
Enjoy, test, and report!
PS: at the risk of losing credibility, I’ll remark, once again, my intention to rewrite this software. I swear I have made a decision this time: it is going to be rewritten in Go. I have already started playing with the language (soon some posts about it) and designing the new software.
A few days ago Ian Barber wrote an article about the automated spelling correction.
Today I had the time to read it. Good quality and great presentation as always. However, the first thing I noticed is that the solution presented by Ian was not making use of the Soundex algorithm at all, which seemed slightly strange to me according to my experience. So, I have quickly refined that solution using the standard soundex() PHP function.
I’ve just uploaded a technical report I wrote months ago, almost a year now. You can find it filed under my Publications page. The full title is “Clustering and classification in Information Retrieval: from standard techniques towards the state of the art“. I wrote this report when I was working for the SoLCo project at the University of Naples “Federico II”. SoLCo was an applied research project that aimed at bringing the state of the art of the information retrieval techniques to the Public Administration.
Information Retrieval is a wide branch. My role was to research and apply mainly clustering techniques, but also classification methodologies. This report was written at the early stages of the project.
While I still did not find the time to rewrite LIBSVM in the way I would like, I keep updating my LIBSVM Plus, back-porting the latest changes from the head version (2.89 this time) of the classic LIBSVM.
This release is nothing more than a merge with classic LIBSVM code updates. All the “plus” features are the same of the previous (2.88) version.
Enjoy, test, and report!
PS: I have the intention of writing a PHP extension for LIBSVM (Plus), so, hopefully, I will finally rewrite LIBSVM too.
Zotero [zoh-TAIR-oh] is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work — in the web browser itself.
Especially if you are a researcher (and of course if you like to use Firefox, which I don’t, lately), this extension will make your day.
Basically, Zotero is a complete bibliography manager with some exceptional features which it can provide us with thanks to the integration with Firefox:
Looks really great anyway, even if I am not gonna use it, because I prefer a browser to browse internet, not an application container “wanna-be” (aka Firefox).
With a huge delay, I’ve finally released the new version of LIBSVM Plus, back-porting the latest changes from the head version (2.88) of the classic LIBSVM.
This release is nothing more than a merge with classic LIBSVM code updates. All the “plus” features are the same of the previous (2.86) version.
Enjoy, test, and report!
Xunkai Wei, which is one on the most interested guy in LIBSVM Plus, has recently released a MATLAB interface for my LIBSVM Plus.
I wish to thank him once again for his support and participation.
While I keep testing the novel kernels I previously mentioned, I decided to upgrade the current package of LIBSVM Plus by adding a slightly modified version of the python tools already provided by original LIBSVM. Plus, I added two scripts originally created by Hsuan-Tien Lin.
Fore more details, take a look to the LIBSVM Plus page under the “Updated python tools” and “More python tools” sections.
See you soon for news about the kernels.
Hello guys, it is not so long that I released LIBSVM Plus, but I am about to release a minor update which introduce new kernels. Some of them are well known in literature and are probabilistic kernels. The other ones are, at the best of my knowlegde, novel kernels and I’ll release them only when I will sure about experimental and theoretical results (but such a stuff is quite complete).
Stay tuned.
