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.
Particularly, the …

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 …
