inverse_projection.composed_projector: 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 composed_projector
inverse_projection(x, ...)

Value

A matrix representing the combined pseudo-inverse.

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.
