[jira] [Commented] (SPARK-26247) SPIP - ML Model Extension for
no-Spark MLLib Online Serving
[ https://issues.apache.org/jira/browse/SPARK-26247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16782494#comment-16782494 ]
Sean Owen commented on SPARK-26247:
-----------------------------------
I tend to think of this problem as about as solved as it will be by MLeap. There just hasn't been a representation that 'rules them all', so a library to translate Spark models is probably about as good as it gets. PMML is the best shot at a format and it doesn't cover enough; PFA seems similar in this regard.
