> Components: APIs

>
> Previous instantiations of text analytics usecases with SystemML used to
> communicate feature vectors to SystemML using a 3-column
> table/relation/matrix (see SYSTEMML-452 for a detailed description). The
> first column was defined to be an integer representing a global feature
> vector ID. Creating global integer IDs is hard and time consuming. Can this
> be relaxed to a globally unique string ID instead?
> SystemML's transform operation will be able to handle the above usecase, but
> for reasons related to uniformly handling both features and labels (uniformly
> transforming both X and y matrices) we will need to update transform (or
> introduce some equivalent functionality) that allows one to apply an already
> created recode map and recode from scratch on the same matrix.
