It has a cool history, but to write my study notes, I just needed to figure out how to use it in these blog posts. A WordPress blog hosted at wordpress.com already has support for LaTeX available. For a self-hosted site like this, I searched for a plugin. There are quite a few; I settled on QuickLaTeX.
I want to spend my time focusing on machine learning, not how to use so please forgive the odd layout. It should improve as I move forward with my learning.
