The theoretical analysis of the effects of truncating the computation of WESD at N modes on the low-dimensional embeddings: Points (markers) indicate the low-dimensional embeddings obtained by using ρ^N(·, ·). The rectangle around a point denotes the theoretical maximum extent that point might move to if infinite number of modes were used to compute the distance, i.e. if ρ(·, ·) were used. These bounds are computed using using Equation 9 without the need to compute more eigenvalues than N.
