StableMDS: A Novel Gradient Descent-Based Method for Stabilizing and Accelerating Weighted Multidimensional Scaling

Multidimensional Scaling (MDS) is an essential technique in multivariate analysis, with Weighted MDS (WMDS) commonly employed for tasks such as dimensionality reduction and graph drawing. However, the optimization of WMDS poses significant challenges due to the highly non-convex nature of its object…
