ApplyPCATransformation
Applies previously obtained PCA transformation coefficients to new data.
Syntax
void avl::ApplyPCATransformation ( const avl::Matrix& inMatrix, const avl::PCAModel& inPCAModel, avl::Matrix& outTransformedMatrix )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inMatrix | const Matrix& | Input data with variables in columns and examples in rows. | |
|
inPCAModel | const PCAModel& | Previously created PCA model to apply to data provided in inMatrix. | |
 |
outTransformedMatrix | Matrix& | Transformed inMatrix. |
Errors
| Error type | Description |
|---|---|
| DomainError | Malformed inPCAModel - MeanVector and StandardDeviationVector have to have the same length! |
| DomainError | Malformed inPCAModel - MeanVector and StandardDeviationVector are not row-vectors! |
| DomainError | PCAModel does not match - inMatrix column count does not match! |
| DomainError | PCAModel does not match - StandardDeviationVector length is different then inMatrix column count! |
| DomainError | PCAModel does not match - PCAFeatureVector dimensions does not correspond to inMatrix dimensions! |
