Anscombe’s quartet is a set of four toy datasets that look very
different, but many of their statistics coincide. They were developed by
Francis Anscombe as a striking visual to show that even for small
datasets, blindly examining their statistical properties without
considering their structure can mislead.

This summer I hope to be able to put in another full-time amount of
effort into scikit-learn. After a successful Google Summer of Code
project last year on dictionary learning, I now plan to do some
low-level work. The title of my proposal is: “Need for scikit-learn
speed” and, in …

A while back, Bob L. Sturm blogged about a similar implementation of
OMP to the one in scikit-learn. Instead of using the Cholesky
decomposition like we did, his Matlab code uses the QR decomposition, to
a similar (or maybe even identical) outcome, in theory. So lucky that
Alejandro pointed out …
