  2. Repeat the operations described previously over the tModelEncoder labelled Tokenizer to add the sms_tf_vect column of the Vector type to the output schema and define the
    transformation as displayed in the image above.

    In this transformation, tModelEncoder
    uses HashingTF to convert the already
    tokenized SMS messages into fixed-length (15 in this scenario) feature vectors to reflect the importance
    of a word in each SMS message.
