trustworthiness_score

Function that calculates the trustworthiness score of a UMAP dimensionality reduction

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.

the quality of UMAP dimensionality reduction results" (2025, in preparation).
