inverse_projection.composed_projector: Compute the Inverse Projection for a Composed Projector

In bbuchsbaum/multivarious: Extensible Data Structures for Multivariate Analysis

Compute the Inverse Projection for a Composed Projector

Description

Calculates the pseudo-inverse of the composed projector, mapping from the final output space back towards the original input space. This is computed by multiplying the pseudo-inverses of the individual projector stages in reverse order: ⁠V_k+ %*% ... %*% V_2+ %*% V_1+⁠.

Usage

## S3 method for class 'composed_projector'
inverse_projection(x, ...)

Arguments

x	A composed_projector object.
...	Additional arguments passed to the underlying inverse_projection methods.

Details

Requires that each stage implements the inverse_projection method.

Value

A matrix representing the combined pseudo-inverse.
