UMAP.
- selimthegrim 5y agoObligatory Lior Pachter tweet (https://twitter.com/lpachter/status/1431325969411821572 https://twitter.com/lpachter/status/1431325969411821572) [doesn't mention issue of initialization explictly but it's probably buried in the paper or the cited tweets]
- prionassembly 5y agoYeah. I was kind of infatuated with the UMAP paper when it first came up (and working through it to build intuition led me to persistent homology and other fun stuff), but it's far too complex to work as a "plug-in tool" that people naive to statistics can blindly use. This is the power of ANOVA, CCA, linear regression and factor analysis, etc. It's much, much, much, much harder to shoot yourself in the foot, particularly with experimental data (usage in the social sciences is another bag of johnsons.)
