Fig. 2From: Anonymisation of geographical distance matrices via Lipschitz embeddingInfluence of Lipschitz embedding on two different data analysis tasks. The left plot shows the rate of correct nearest neighbour classifications depending on parameters d and k of the Lipschitz embedding. The right plot shows the Spearman correlation \(\rho\) between original and approximated distances for different choices of d and k of all distances in the data files to two fixed points. The black lines refer to a fixed point in the centre of England whereas the grey lines refer to a fixed point in the north of EnglandBack to article page
