Python at scientific conferences

Top notch scientific conferences are starting to add Python tracks to their program. This is good news. Indeed, it scientific Python conferences (namely Scipy, EuroSciPy and Scipy India) are doing great to get together people who have already heard about Python for science, but we need to reach out to ...

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 ...

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 ...

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 ...

Sprint Scikit learn in Paris

We are organizing a coding sprint in Paris on scikit learn, machine learning in Python. The goal of this sprint is to set the API and the general coding guidelines of the scikit to be able to tackle many different statistical learning problems in a consistent framework.

This is why ...

Simple object signatures

A signature pattern

There are many libraries around to specify what I call a ‘signature’ for an object, in other words a list of attributes that define its parameter set. I have heavily used Enthought’s Traits library for this purpose, but the concept is fairly general and can be ...
