Polygonal Coordinate System: Visualizing high-dimensional data using geometric DR, and a deterministic version of t-SNE

作者:

Highlights:

• A global geometric approach for embedding-based dimensionality reduction in 2D/3D.

• An effcient method across a regular polygon named Polygonal Coordinate System (PCS).

• A deterministic version of t-SNE is proposed to explore the strengths of PCS + t-SNE.

• PCS can properly handle large amounts of data without in-memory loading limitations.

• Comparative studies show that PCS outperforms previous techniques in many aspects.
