DesignMatrix-class: A design matrix
In sanmai-NL/feat: Extract (Linguistic) Structural and Surface Features from XML Documents
Description
A design matrix
Slots
DMATA design matrix with feature scores, with objects as rows indexed by their object_ID and named columns as features. May contain a column named the empty string, with all-zero values (DUMMY_OBJECT_FEATURES_DVEC in the code). This is the case when from one or more objects no structural features could be extracted given the feature representation parameters.
LOWER_RANK_APPROXIMATION_DMATA lower rank approximation of DMAT, based on SVD. See: FeatureRepresentation.
SVDA Singular Value Decomposition (SVD) of DMAT as returned by svd. Will be NULL if SVD has not been applied (FeatureRepresentation).
