Saving the classifier to a file

Finally, we can write out our classifier to a file using clj-ml.utils/serialize-to-file:

(defn ex-4-48 []
  (let [dataset (->> (load-data "titanic.tsv")
                     (to-weka)
                     (mlf/make-apply-filter
                      :replace-missing-values {}))
        classifier (cl/make-classifier :decision-tree
                                       :random-forest)
        file (io/file (io/resource "classifier.bin"))]
    (clu/serialize-to-file classifier file)))

At some point later, we can load up our trained classifier using the clj-ml.utils/deserialize-from-file and immediately begin classifying new data.
