public interface EigenPairFilter
extends Parameterizable

The eigenpair filter is used to filter eigenpairs (i.e. eigenvectors and their corresponding eigenvalues) which are a result of a Variance Analysis Algorithm, e.g. Principal Component Analysis. The eigenpairs are filtered into two types: strong and weak eigenpairs, where strong eigenpairs having high variances and weak eigenpairs having small variances.

Method Summary

FilteredEigenPairs

filter(SortedEigenPairs eigenPairs) Filters the specified eigenpairs into strong and weak eigenpairs, where strong eigenpairs having high variances and weak eigenpairs having small variances.
