Abstract: The Healy-McInnes UMAP algorithm is a highly successful clustering tool that involves interesting ideas from mathematics and data science:
1) Spivak's theory of extended pseudo metric spaces (ep-metric spaces) 2) TDA constructions in ep-metric spaces 3) weighted graphs 4) classical dimension reduction 5) graph optimization: fuzzy sets, cross entropy
I will explain the algorithm from a mathematical point of view.
