Scikit-learn sprint on April 1st

The scikit-learn team is organizing a sprint on April 1st (that next Friday). Join us in Paris, Boston, or on IRC!

With the rise of the data sciences, the scikit-learn, a BSD-licensed Python package for machine learning, is becoming an asset for more and more endeavors. Machine learning has traditionally …

Windows binaries for the scientific Python ecosystem

I just realized yesterday that Christoph Gohlke has a repository of binary installers (.exe) for Windows 32 and 64bit with almost all the scientific Python packages that you can dream of:

  • numpy, scipy and matplotlib, of course (compiled with the MKL)
  • cython
  • the ETS, including Mayavi
  • VTK, with the Python …

Interested in parallel computing and statistics? We are looking for a post-doc

My research group is kick starting a new project, called AzureBrain to do computational analysis of large brain imaging and genetics population-wise data. One of the goals of the project is to harness the power of grid computing to do statistical learning on fMRI data, finding features in an individuals …

Scientific publication for software development

The academic community seems to judge the validity and significance of any contribution by the number of papers published and the number of citations they get. To find funding, to get credit, you have to publish or perish. However, the natural output of software development tends not to be an …

ICA versus PCA in the scikit-learn: the value of code over pictures

When I was trying to get an intuitive feeling of the difference between Independent Component Analysis (ICA) and Principal Component Analysis (PCA), I wrote a few Python scripts producing some visualizations explaining the difference that have had a bit of success.

During the last sprint on scikit-learn, a machine learning …

Multitouch with VTK (and MedINRIA and Mayavi)

If the videos on this post are not showing, click through to see them.

A colleague of mine, Pierre Fillard, has just integrated multitouch in the next generation of the VTK-based medical imaging software MedINRIA. The nice thing is that it works on an Apple laptop out of the box …

Machine learning humour

Yes, but they overfit

If you are reading this post through a planet, the movie isn’t showing up, just click through to understand what the hell this is about.

Some explanations…

Machine learning, geeks, and beers

Sorry for the bad humour. In the previous weeks my social geek life …

Scikit Learn coding sprint

We have been really crap at communicating the next scikit-learn coding sprint. It’s next week!

The coding sprint will take place the 8 and 9 September at INRIA Saclay, near Paris, in the room K110 (building K).

For those who cannot make it, it will be possible to participate …

SVG Word map of countries

To be able to visualize some quantities attached to countries all over the world, I needed a image with various countries color-coded. The fantastic matplotlib basemap package was not an option as I really needed a static image.

So I generated an SVG image with all the countries. It was …

Software design for maintainability

I have just spent the best part of my Sunday fixing a bug that turned out being a seemingly-trivial two-liner. Such unpleasant experiences are all too frequent, and weight a lot on my view of code design.

My stance on code design

I call code design the process of designing …

Euroscipy 2010: code, science, and a lot of fun

Status of the EuroScipy registration

It is still not possible to register for the Euroscipy conference: we are having difficulties with payment for the registration, and we are still not sure that we will be able to actually charge money!

This might not be a bad news, because it might mean that the conference will …

Book review: Matplotlib for Python Developpers

Packt publishing sent me a copy of Sandro Tosi’s book Matplotlib for Python Developpers a while ago. Unfortunately, it arrived after I had left for the Christmas break, and I couldn’t find time to review it for a while (I am terribly bad at time-management, and I do …
