Reconstruct Data from Scores using a Composed Projector — reconstruct.composed

Maps scores from the final latent space back towards the original input space using the composed projector's combined inverse projection. Requires scores to be provided explicitly.

Usage

# S3 method for class 'composed_projector'
reconstruct(x, scores, comp = NULL, rowind = NULL, colind = NULL, ...)

Arguments

x: A composed_projector object.
scores: A numeric matrix of scores (observations x components) in the final latent space of the composed projector.
comp: Numeric vector of component indices (columns of scores, rows of inverse_projection) to use for reconstruction. Defaults to all components.
rowind: Numeric vector of row indices (observations in scores) to reconstruct. Defaults to all rows.
colind: Numeric vector of original variable indices (columns of the final reconstructed matrix) to return. Defaults to all original variables.
...: Additional arguments (currently unused).

Value

A matrix representing the reconstructed data, ideally in the original data space.

Details

Attempts to apply the reverse_transform of the first stage's preprocessor to return data in the original units. If the first stage preprocessor is unavailable or invalid, a warning is issued, and data is returned in the (potentially) preprocessed space of the first stage.
