AVL.ReversePCATransform Method

Reverses Principal Component Analysis (PCA) process. Can be used to transform data back to original feature space.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

public static void ReversePCATransform(
	AvlNet.Matrix inTransformedMatrix,
	AvlNet.PCAModel inPCAModel,
	out AvlNet.Matrix outMatrix
)

Name	Type	Description
inTransformedMatrix	AvlNet.Matrix	Data that was transformed earlier.
inPCAModel	AvlNet.PCAModel	PCA model used to create inTransformedMatrix.
outMatrix	AvlNet.Matrix	inTransformedMatrix transformed back to its original feature space.

Error type	Description
DomainError	Feature vector of inPCAModel and Transformed Data matrices dimensions do not correspond to each other in ReversePCATransform.
DomainError	Malformed inPCAModel - uneven vector sizes in ReversePCATransform.
DomainError	Malformed inPCAModel - MeanVector is not row-vector in ReversePCATransform.
DomainError	Malformed inPCAModel - StandardDeviationVector is not row-vector in ReversePCATransform.
DomainError	inMeanVector and inStandardDeviationVector have incorrect size for inTransformedMatrix provided in ReversePCATransform.
