why MatrixFactorizationModel private?
Hi all, seems that all the mllib models are declared accessible in the package, except MatrixFactorizationModel, which is declared private to mllib. Any reason why? thanks, -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/why-MatrixFactorizationModel-private-tp19763.html Sent from the Apache Spark User List mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
Re: why MatrixFactorizationModel private?
Besides API stability concerns, models constructed directly from users rather than returned by ALS may not work well. The userFeatures and productFeatures are both with partitioners so we can perform quick lookup for prediction. If you save userFeatures and productFeatures and load them back, it is very likely the partitioning info is missing. That being said, we will try to address model export/import in v1.3: https://issues.apache.org/jira/browse/SPARK-4587 . -Xiangrui On Tue, Nov 25, 2014 at 8:26 AM, jamborta jambo...@gmail.com wrote: Hi all, seems that all the mllib models are declared accessible in the package, except MatrixFactorizationModel, which is declared private to mllib.
