At Spark Summit, Patrick Wendell indicated the number of MLlib algorithms would "roughly double" in 1.1 from the current approx. 15. http://spark-summit.org/wp-content/uploads/2014/07/Future-of-Spark-Patrick-Wendell.pdf
What are the planned additional algorithms? In Jira, I only see two when filtering on version 1.1, component MLlib: one on multi-label and another on high dimensionality. https://issues.apache.org/jira/browse/SPARK-2329?jql=issuetype%20in%20(Brainstorming%2C%20Epic%2C%20%22New%20Feature%22%2C%20Story)%20AND%20fixVersion%20%3D%201.1.0%20AND%20component%20%3D%20MLlib http://tinyurl.com/ku7sehu
