* [SPARK-14615][ML][FOLLOWUP] Fix Python examples to use the new ML Vector and ↵hyukjinkwon2016-06-1010-19/+18
| | | | | | | | | | | | | | | | | | | | | | | | | Matrix APIs in the ML pipeline based algorithms ## What changes were proposed in this pull request? This PR fixes Python examples to use the new ML Vector and Matrix APIs in the ML pipeline based algorithms. I firstly executed this shell command, `grep -r "from pyspark.mllib" .` and then executed them all. Some of tests in `ml` produced the error messages as below: ``` pyspark.sql.utils.IllegalArgumentException: u'requirement failed: Input type must be VectorUDT but got org.apache.spark.mllib.linalg.VectorUDTf71b0bce.' ``` So, I fixed them to use new ones just identically with some Python tests fixed in https://github.com/apache/spark/pull/12627 ## How was this patch tested? Manually tested for all the examples listed by `grep -r "from pyspark.mllib" .`. Author: hyukjinkwon <gurwls223@gmail.com> Closes #13393 from HyukjinKwon/SPARK-14615.
* [SPARK-15771][ML][EXAMPLES] Use 'accuracy' rather than 'precision' in many ↵Yanbo Liang2016-06-066-12/+12
| | | | | | | | | | | | | | | | | | ML examples ## What changes were proposed in this pull request? Since [SPARK-15617](https://issues.apache.org/jira/browse/SPARK-15617) deprecated ```precision``` in ```MulticlassClassificationEvaluator```, many ML examples broken. ```python pyspark.sql.utils.IllegalArgumentException: u'MulticlassClassificationEvaluator_4c3bb1d73d8cc0cedae6 parameter metricName given invalid value precision.' ``` We should use ```accuracy``` to replace ```precision``` in these examples. ## How was this patch tested? Offline tests. Author: Yanbo Liang <ybliang8@gmail.com> Closes #13519 from yanboliang/spark-15771.
* [SPARK-15031][EXAMPLES][FOLLOW-UP] Make Python param example working with ↵hyukjinkwon2016-05-191-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | SparkSession ## What changes were proposed in this pull request? It seems most of Python examples were changed to use SparkSession by https://github.com/apache/spark/pull/12809. This PR said both examples below: - `simple_params_example.py` - `aft_survival_regression.py` are not changed because it dose not work. It seems `aft_survival_regression.py` is changed by https://github.com/apache/spark/pull/13050 but `simple_params_example.py` is not yet. This PR corrects the example and make this use SparkSession. In more detail, it seems `threshold` is replaced to `thresholds` here and there by https://github.com/apache/spark/commit/5a23213c148bfe362514f9c71f5273ebda0a848a. However, when it calls `lr.fit(training, paramMap)` this overwrites the values. So, `threshold` was 5 and `thresholds` becomes 5.5 (by `1 / (1 + thresholds(0) / thresholds(1)`). According to the comment below. this is not allowed, https://github.com/apache/spark/blob/354f8f11bd4b20fa99bd67a98da3525fd3d75c81/mllib/src/main/scala/org/apache/spark/ml/classification/LogisticRegression.scala#L58-L61. So, in this PR, it sets the equivalent value so that this does not throw an exception. ## How was this patch tested? Manully (`mvn package -DskipTests && spark-submit simple_params_example.py`) Author: hyukjinkwon <gurwls223@gmail.com> Closes #13135 from HyukjinKwon/SPARK-15031.

| | | | | | | | | | | | examples and user guide doc ML ```LinearRegression``` use ```data/mllib/sample_libsvm_data.txt``` as dataset in examples and user guide doc, but it's actually classification dataset rather than regression dataset. We should use ```data/mllib/sample_linear_regression_data.txt``` instead. The deeper causes is that ```LinearRegression``` with "normal" solver can not solve this dataset correctly, may be due to the ill condition and unreasonable label. This issue has been reported at [SPARK-11918](https://issues.apache.org/jira/browse/SPARK-11918). It will confuse users if they run the example code but get exception, so we should make this change which can clearly illustrate the usage of ```LinearRegression``` algorithm.
