[jira] [Commented] (SPARK-9695) Add random seed Param to ML
Pipeline
[ https://issues.apache.org/jira/browse/SPARK-9695?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14937046#comment-14937046 ]
Yanbo Liang commented on SPARK-9695:
------------------------------------
[~josephkb]
I agree to make HasSeed the main API to decide whether an algorithm takes a seed.
I propose to make PipelineStage extends from HasSeed and all meta-algs will get the same seed and can have reproducible results for entire pipelines. Please correct me if I have some misunderstands.
