Hi Imk, I am not aware of any classifier in MLLib that accept nominal type of data. They do accept RDD of LabeledPoints, which are label + vector of Double. So, you'll need to convert nominal to double.

Should I be following the same procedure even if my data is nominal (categorical), but having a lot of combinations? (In Weka I used to have it as nominal data) Regards, -lmk -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Prediction-using-Classification-with-text-attributes-in-Apache-Spark-MLLib-tp8166p8249.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
