Hi all, Zhipeng and I have created FLIP-175: Compose Estimator/Model/AlgoOperator from DAG of Estimator/Model/AlgoOperator. Please find the FLIP wiki in the link https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=181311363.
With this FLIP, users can compose an Estimator from a DAG of Estimator/Model/AlgoOperator by describing this DAG just once without having to separately describe the DAG for the Model fitted by this Estimator. It will be really helpful if you can help review this FLIP and provide your feedback. Thanks! Dong and Zhipeng
