-----------------------------------------
Summary: Various ML programming guide cleanups post 1.5
Key: SPARK-10595
URL: https://issues.apache.org/jira/browse/SPARK-10595
Project: Spark
Issue Type: Documentation
Components: Documentation, ML, MLlib
Affects Versions: 1.5.0
Reporter: Joseph K. Bradley
Assignee: Joseph K. Bradley
Priority: Minor
Various ML guide cleanups.
* ml-guide.md: Make it easier to access the algorithm-specific guides.
* LDA user guide: EM often begins with useless topics, but running longer
generally improves them dramatically. E.g., 10 iterations on a Wikipedia
dataset produces useless topics, but 50 iterations produces very meaningful
topics.
* mllib-feature-extraction.html#elementwiseproduct: “w” parameter should be
“scalingVec”
* Clean up Binarizer user guide a little.
* Document in Pipeline that users should not put an instance into the Pipeline
in more than 1 place.
* spark.ml Word2Vec user guide: clean up grammar/writing
* Chi Sq Feature Selector docs: Improve text in doc.
