and the color here indicates the energy so the energy is low on the manifold which is what you want it's high outside except there's a problem right here there's a ridge here and it's a it's a kind of a flat Ridge which is not good so here the reconstruction error is actually zero because the system when this train doesn't can't decide whether to go this way or that way so there's a flaw with this with this thing there ways to fix it but no clear the main issue with this is that it doesn't scale with well in high dimension because in
