Feature Description with LDA Matrix

This means that you have to add one line to the feature description. Your 'final' feature will now be the result of a 'matmul' method applied to the LDA-source feature. This one additional line looks like:

  $fes    matmul  LDAin    LDAout   matrixCD

If you want the LDA to also do a dimensionality reduction, you can cut off the less important coefficients (the coefficients with small eigenvalues) by adding a line like:

  $fes    split   LDAout   finalFeature  0   15

See the page for the feature description file for details.
