SaturnCoefficient (version 1.6)
Statistical Evaluation of UMAP Dimensionality Reductions
Description
A metric expressing the quality of a UMAP layout. This is a
package that contains the Saturn_coefficient() function that reads an
input matrix, its dimensionality reduction produced by UMAP, and
evaluates the quality of this dimensionality reduction by producing a
real value in the [0; 1] interval. We call this real value Saturn
coefficient. A higher value means better dimensionality reduction; a
lower value means worse dimensionality reduction.
