Key Points

  • The aim is to establish a robust formulation of multidimensional scaling influenced by Gaussian noise in distance measurements.
  • Developed a stress objective function from a probabilistic model.
  • Analyzed the effects of independent additive Gaussian noise on pairwise distances.
  • Proved the consistency of the estimator under noise reduction.
  • Derived finite-sample probability bounds on estimation error.
  • Established the estimator remains consistent as noise vanishes.
  • Provided theoretical bounds on estimation errors for finite samples.
  • Indicated improved accuracy of multidimensional scaling with better distance measurements.

Abstract

This work establishes a formulation of the classical multidimensional scaling in which the pairwise distances are corrupted by independent additive Gaussian noise. This formulation yields a stress objective function, derived from an explicit probabilistic model, allowing for a rigorous statistical analysis. Up to rotations and translations, we also prove the consistency of the estimator when the noise vanishes and prove finite-sample probability bounds on the estimation error. Our results complement the recently developed theories by focusing on a fixed size of data with increasingly accurate distance measurements.
