    Default Singular Value Decomposition Weka

    Hello,
    Where's the SVD (Singular Value Decomposition) in Weka? I know the SVD function is weka.core.matrix.SingularValueDecomposition But I don't know where to find in software weka.
    Thank you

    Weka does not have a SVD-based filter (if that is what you are referring to). However, it does have PCA (as both an attribute selection method and a filter). This can work by computing either a correlation or covariance matrix. The filter can transform the input data into the PCA space, which is basically the same as SVD I believe.

    Cheers,
    Mark.
