Kian Ho created SPARK-6340:
------------------------------
Summary: mllib.IDF for LabelPoints
Key: SPARK-6340
URL: https://issues.apache.org/jira/browse/SPARK-6340
Project: Spark
Issue Type: Improvement
Components: MLlib
Affects Versions: 1.3.0
Environment: python 2.7.8
pyspark
OS: Linux Mint 17 Qiana (Cinnamon 64-bit)
Reporter: Kian Ho
Priority: Minor
as per:
http://apache-spark-user-list.1001560.n3.nabble.com/Using-TF-IDF-from-MLlib-td19429.html#a19528
Having the IDF.fit accept LabelPoints would be useful since, correct me if i'm
wrong, there currently isn't a way of keeping track of which labels belong to
which documents if one needs to apply a conventional tf-idf transformation on
text data.
