When visualizing a high-dimensional dataset, dimension reduction techniques are commonly employed which provide a single 2-dimensional view of the data.

Dimensionality Reduction

Multi-Perspective, Simultaneous Embedding

1 code implementation • 13 Sep 2019 • Md Iqbal Hossain, Vahan Huroyan, Stephen Kobourov, Raymundo Navarrete

MPSE with fixed projections takes as input a set of pairwise distance matrices defined on the data points, along with the same number of projections and embeds the points in 3D so that the pairwise distances are preserved in the given projections.
