byte-array->model clj

(byte-array->model data)

dataset->dmatrix clj

(dataset->dmatrix dataset feature-keys label-key)

Dataset is a sequence of maps. Each contains a feature key. Returns a dmatrix.

dataset->labeled-point-iterator clj

(dataset->labeled-point-iterator dataset
                                 &
                                 {:keys [weight group]
                                  :or {weight 1.0 group -1}})

Create an iterator to labeled points from a possibly quite large sequence of maps. Sets expected length to length of first entry
