yuhao yang created SPARK-20271: ---------------------------------- Summary: Add FuncTransformer to simplify custom transformer creation Key: SPARK-20271 URL: https://issues.apache.org/jira/browse/SPARK-20271 Project: Spark Issue Type: New Feature Components: ML Affects Versions: 2.2.0 Reporter: yuhao yang
Just to share some code I implemented to help easily create a custom Transformer in one line of code w. {code} val labelConverter = new FuncTransformer((i: Double) => if (i >= 1) 1 else 0) {code} This was used in many of my projects and is pretty helpful (Maybe I'm lazy..). The transformer can be saved/loaded as other transformer and can be integrated into a pipeline normally. It can be used widely in many use cases and you can find some examples in the PR. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
