PCA Inversion

This node reverses the transformation applied by the PCA Apply node. It takes data from the PCA-reduced space and transforms it back into the original feature space using the same PCA model. Note that the reconstruction is only an approximation of the original data, since any information lost during the PCA reduction cannot be recovered.

Options

Columns

Remove selected columns

If checked, the selected columns are removed in the output table.

Fail if missing values are encountered

If checked, execution fails when the selected columns contain missing values. By default, rows with missing values are ignored and excluded from the computation.
