Subject [jira] [Commented] (SPARK-5207) StandardScalerModel mean and variance re-use
Date Tue, 13 Jan 2015 06:36:35 GMT

    [ https://issues.apache.org/jira/browse/SPARK-5207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14274802#comment-14274802

DB Tsai commented on SPARK-5207:
--------------------------------

[~mengxr]'s idea sounds great for me. Specifically, let's have mean and variance as required
variables in the constructor, and have withMean = false, and withStd = true as default variables.
Add another two methods to change withMean and withStd. Thanks.

> Changing constructor to public would be a simple change, but a discussion is needed to
determine what args necessary for this change.
