PCA & TableOfReal: To Configuration...

A command to construct a Configuration from the selected TableOfReal and PCA.

Setting

Number of dimensions
determines the number of dimensions of the resulting Configuration.

Algorithm

The TableOfReal is projected on the eigenspace of the PCA, i.e., each row of the TableOfReal is treated as a vector, and the inner product with the eigenvectors of the PCA determine its coordinates in the Configuration.

Because the algorithm performs a projection, the resulting Configuration will only be centered, i.e., its centroid will be at 0, if the data in the TableOfReal object are centered too.
