* [SPARK-12296][PYSPARK][MLLIB] Feature parity for pyspark mllib standard ↵Holden Karau2015-12-221-0/+40
| | | | | | | | | | scaler model Some methods are missing, such as ways to access the std, mean, etc. This PR is for feature parity for pyspark.mllib.feature.StandardScaler & StandardScalerModel. Author: Holden Karau <holden@us.ibm.com> Closes #10298 from holdenk/SPARK-12296-feature-parity-pyspark-mllib-StandardScalerModel.
* [SPARK-12380] [PYSPARK] use SQLContext.getOrCreate in mllibDavies Liu2015-12-161-3/+1
| | | | | | | | MLlib should use SQLContext.getOrCreate() instead of creating new SQLContext. Author: Davies Liu <davies@databricks.com> Closes #10338 from davies/create_context.
* [SPARK-12016] [MLLIB] [PYSPARK] Wrap Word2VecModel when loading it in pysparkLiang-Chi Hsieh2015-12-141-1/+5
| | | | | | | | | | JIRA: https://issues.apache.org/jira/browse/SPARK-12016 We should not directly use Word2VecModel in pyspark. We need to wrap it in a Word2VecModelWrapper when loading it in pyspark. Author: Liang-Chi Hsieh <viirya@appier.com> Closes #10100 from viirya/fix-load-py-wordvecmodel.
* [SPARK-10273] Add @since annotation to pyspark.mllib.featurenoelsmith2015-09-141-1/+57
| | | | | | | | | | Duplicated the since decorator from pyspark.sql into pyspark (also tweaked to handle functions without docstrings). Added since to methods + "versionadded::" to classes (derived from the git file history in pyspark). Author: noelsmith <mail@noelsmith.com> Closes #8633 from noel-smith/SPARK-10273-since-mllib-feature.
