A journal promoting high-quality research code: dream and reality
Open research computation (ORC) was an attempt to create a scientific publication promoting high-quality and open source scientific code. The project went public in falls 2010, but last month, facing the low volume of submission, the editorial board chose to reorient it as a special track of an existing journal …
Update on scikit-learn: recent developments for machine learning in Python
Yesterday, we released version 0.11 of the scikit-learn toolkit for machine learning in Python, and there was much rejoincing.
Major features gained in the last releases
In the last 6 months, there have been many things happening with the scikit-learn. While I do not whish to give an exhaustive …
The problems of low statistical power and publication bias
Lately, I have been a mood of scientific scepticism: I have the feeling that the worldwide academic system is more and more failing to produce useful research. Christophe Lalanne’s twitter feed lead me to an interesting article in a non-mainstream journal: A farewell to Bonferroni: the problems of low …
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 …
Conference posters
At the request of a friend, I am putting up some of the posters that I recently presented at conferences.
Large-scale functional-connectivity graphical models for individual subjects using population prior.
This is a poster for our NIPS work

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 …

Research jobs in France: the black humor of 2010 is the reality of 2011
The French basic research landscape is dominated by a few nationwide institute, similar to the NIST or the NIH in the US. The largest of these is the CNRS (Centre National de la Recherche Scientific). Getting a tenured job in one of those institutes enables someone to focus on basic …
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 …
Euroscipy 2010: code, science, and a lot of fun
Euroscipy 2010, the third European conference for the use of Python in science, is just over, and I think it was a great success.

Personal views on scientific computing
My contributions to the scientific computing software ecosystem are motivated by my vision on computational science.
Scientific research relies more and more on computing. However, most of the researchers are not software engineers, and as computing is becoming ubiquitous, the limiting factor becomes more and more the human factor [G …
