So what is this blog all about?

Updated 2019-03-03

If you can’t explain it simply, you don’t understand it well enough. - Albert Einstein

The purpose of this blog is two fold

  1. Learn better by following Feynman Technique
  2. Organize plethora of information I deem worth preserving for purpose of knowledge sharing and recall.

The blog is broadly organized into following cateories:

Tensor Algebra

A short course (WIP) to build solid foundation in Tensor Algebra, which is a prerequisite to Tensor Calculus, which itself is a prerequisite to Differential Geometry, which in turn forms the mathematical language for Einstein's General Theory of Relativity.

Machine Learning

Different Machine learning topics, including an archive of interesting papers.
