# Inverses and pseudoinverses. Numerical issues, speed, symmetry.

The matrix inverse is a cornerstone of linear algebra, taught, along with its applications, since high school. The inverse of a matrix \$latex A\$, if it exists, is the matrix \$latex A\^{-1}\$ such that \$latex AA\^{-1} = A\^{-1}A = I_n\$. Based on the requirement that the left and …

# The scikit-learn-speed ship has set sail! Faster than ever, with multi-step benchmarks!

I am pleased to announce that last night at 2:03 AM, the first fully automated run of the scikit-learn-speed test suite has run on our Jenkins instance! You can admire it at its temporary home for now. As soon as we verify that everything is good, we will move …

# Profiler output, benchmark standard deviation and other goodies in scikit-learn-speed

This post is about the scikit-learnbenchmarking project that I am working on, called scikit-learn-speed. This is a continuous benchmarking suite that runs and generates HTML reports using Wes McKinney’s vbench framework, to which I had to make some (useful, I hope) additions.

You …
