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. CC: mengxr feynmanliang Author: Joseph K. Bradley <joseph@databricks.com> Closes #8752 from jkbradley/mlguide-fixes-1.5.
