Topological Initialization for Multidimensional Scaling

Abstract
Multidimensional scaling is a popular technique for visualizing dissimilarities between objects in complex datasets. For a single dataset, different initial configurations for multidimensional scaling may produce representations with qualitatively different features. This presents both challenges and opportunities for those who use these methods. We introduce the new technique Topological Initialization for Multidimensional Scaling (TIMDS) which employs cycle representatives, a tool from topological data analysis, to generate multidimensional scaling initializations. We show that for some datasets, TIMDS produces representations with competitive stress values and better visualization of key dataset attributes compared to random or classical initialization methods.
