A node is a point in the coordinate system with an estimated
position.
Node positions may either be represented Vivaldi coordinate, or by
"hybrid" coordinates. In the hybrid model, an additional
non-Euclidean adjustment term is added to each coordinate.
Adjustment terms improve the performance of the Euclidean
embedding, and therefore can match the performance of
high-dimension embeddings with fewer dimensions (plus the
adjustment term).

Coordinate System" by Lee et al.
