Thank you! Added these to the video description as well!
Concerning the slide at 28:18, I would like to point out that the only stochastic element in tSNE is the initialisation of the low-dimensional embedding: even the accelerated BH algorithm is not stochastic. In other words, tSNE is just as stochastic as UMAP: the result will be the same given the same initialisation.
