I have a lot of horizontal (i = 1:360) and vertical (j = 1:180) values that represents a distance between the … WebFor example, to project onto a 3-sphere, first perform ordinary dimensionality reduction to 2d. Map the resulting points onto a 3-sphere using something like a stereographic projection. If the original data lies on some manifold that's topologically equivalent to a sphere, then it might be more appropriate to perform initial dimensionality ...
