Implement a Feature selector that removes all low-variance features. Features with a variance lower than the threshold will be removed. The default is to keep all features with non-zero variance, i.e. remove the features that have the same value in all samples. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
