I read the t-SNE paper and understood most (well, some) of it.
I see how it can represent the structure of the data at lower dimensions but if I include it in a presentation and someone asks what the axes are for the plot (a common question) I would just have to say it's one of the great mysteries of the Universe - like the meaning of life, or the location of Geoffrey Hinton's highly-advanced homeworld.
I guess that as it is a graph in the graph theory sense it indicates the pairwise relations between the points and so the distance between any two points is a measure of their similarity but it isn't a scatterplot with axes?
Or am I completely wrong?
