A Non-Mathy Introduction to Persistent Homology

October 15, 2019

Working at Geometric Data Analytics, a company full of topologists, I routinely need to write and interpret tools from topological data analysis (TDA). TDA lives in the world of algebraic topology, a blending of abstract algebra and topology. Abstract algebra was never my strong suit, nor have I ever taken a formal topology class, so I wrote non-mathy explanations and examples for one of the tools I use most: persistent homology.
