-------------------------------------
I'm interested in this and would like to take a look.
> Remove breeze from dependencies?
> --------------------------------
>
> Key: SPARK-15575
> URL: https://issues.apache.org/jira/browse/SPARK-15575
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Joseph K. Bradley
>
> This JIRA is for discussing whether we should remove Breeze from the
> dependencies of MLlib. The main issues with Breeze are Scala 2.12 support
> and performance issues.
> There are a few paths:
> # Keep dependency. This could be OK, especially if the Scala version issues
> are fixed within Breeze.
> # Remove dependency
> ## Implement our own linear algebra operators as needed
> ## Design a way to build Spark using custom linalg libraries of the user's
> choice. E.g., you could build MLlib using Breeze, or any other library
> supporting the required operations. This might require significant work.
> See [SPARK-6442] for related discussion.
