scikits.learn coding sprint in Paris
Fabian Pedregosa · 2010-03-04 · via Keep the gradient flowing

Yesterday we had an extremely productive coding sprint for the scikits.learn. The idea was to put people with common interests in a room and make them work in a single codebase. Alexandre Gramfort and Olivier Grisel worked on GLMNet, Bertrand Thirion and Gaël Varoquaux worked on univariate feature selection and Vincent worked on Bayesian Regression.

I was supposed to work with Vincent, but as soon as Bertrand spot some bugs in my libsvm bindings, I could not think of anything except that, and eventually the day finished just as I fixed the bug ... You can find some cool examples of the things we did in directory examples:
