[SPARK-10595] [ML] [MLLIB] [DOCS] Various ML guide cleanups
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: âwâ parameter
should be âscalingVecâ
* 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.
