Tutorials
 ‘Topological Data Analysis for Machine Learning’ at ECML PKDD 2020
Topological Machine Learning is a nascent domain of machine learning research that employ concepts from (applied) topology to improve or analyse machine learning models. I gave a fourpart tutorial on this topic for a general computer science audience that was not necessarily exposed to the mathematical background.
