Trevor et al,

I'd like to contribute an algorithm or two in samsara using spark as I would like to do a compare and contrast with mahout with R server for a data science pipeline, machine learning repo that I'm working on, in looking at the list of algorithms (https://mahout.apache.org/users/basics/algorithms.html) is there an algorithm for spark that would be beneficial for the community, my use cases would typically be around clustering or real time machine learning for building recommendations on the fly.    The algorithms I see that could potentially be useful are: 1) Matrix Factorization with ALS 2) Logistic regression with SVD.

Apache Mahout: Scalable machine learning and data mining<https://mahout.apache.org/users/basics/algorithms.html>
mahout.apache.org
Mahout 0.12.0 Features by Engine¶ Single Machine MapReduce Spark H2O Flink; Mahout Math-Scala Core Library and Scala DSL

Any thoughts/guidance or recommendations would be very helpful.
Thanks in advance.
