I agree with Yu, that you should tell more about your intentions, but possible dirty workaround is create wrapper class for LabeledPoint with all additional information you need and unwrap values before train, and wrap them again after. (look at zipWithIndex - it helps match back additional information after unwrapping)
But I would rather patch my spark with method signature chagnes you suggested. 2014-09-25 18:22 GMT+04:00 Egor Pahomov <pahomov.e...@gmail.com>: > @Yu Ishikawa, > > *I think the right place for such discussion - > https://issues.apache.org/jira/browse/SPARK-3573 > <https://issues.apache.org/jira/browse/SPARK-3573>* > > > 2014-09-25 18:02 GMT+04:00 Yu Ishikawa <yuu.ishikawa+sp...@gmail.com>: > >> Hi Niklas Wilcke, >> >> As you said, it is difficult to extend LabeledPoint class in >> mllib.regression. >> Do you want to extend LabeledPoint class in order to use any other type >> exclude Double type? >> If you have your code on Github, could you show us it?
