From b921fe4dc0442aa133ab7d55fba24bc798d59aa2 Mon Sep 17 00:00:00 2001 From: "Joseph K. Bradley" Date: Tue, 15 Sep 2015 19:43:26 -0700 Subject: [SPARK-10595] [ML] [MLLIB] [DOCS] Various ML guide cleanups MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
