* [SPARK-11815][ML][PYSPARK] PySpark DecisionTreeClassifier & ↵Yanbo Liang2016-01-061-5/+8
| | | | | | | | | | DecisionTreeRegressor should support setSeed PySpark ```DecisionTreeClassifier``` & ```DecisionTreeRegressor``` should support ```setSeed``` like what we do at Scala side. Author: Yanbo Liang <ybliang8@gmail.com> Closes #9807 from yanboliang/spark-11815.

| | | | | | | | [SPARK-7685](https://issues.apache.org/jira/browse/SPARK-7685) and [SPARK-9642](https://issues.apache.org/jira/browse/SPARK-9642) have already supported setting weight column for ```LogisticRegression``` and ```LinearRegression```. It's a very important feature, PySpark should also support. mengxr Author: Yanbo Liang <ybliang8@gmail.com> Closes #9811 from yanboliang/spark-11820.

| | | | | | | | | | | | | | | | | PySpark LinearRegression and LogisticRegression lack of some Params for Python, and some Params are not shared classes which lead we need to write them for each class. These kinds of Params are list here: ```scala HasElasticNetParam HasFitIntercept HasStandardization HasThresholds ``` Here we implement them in shared params at Python side and make LinearRegression/LogisticRegression parameters peer with Scala one.

* [SPARK-5769] Set params in constructors and in setParams in Python ML pipelinesXiangrui Meng2015-02-151-10/+34
| | | | | | | | | | | | | | | | | | | | | | This PR allow Python users to set params in constructors and in setParams, where we use decorator `keyword_only` to force keyword arguments. The trade-off is discussed in the design doc of SPARK-4586.

* [SPARK-4586][MLLIB] Python API for ML pipeline and parametersXiangrui Meng2015-01-281-0/+76
This PR adds Python API for ML pipeline and parameters. The design doc can be found on the JIRA page. It includes transformers and an estimator to demo the simple text classification example code.
