[ https://issues.apache.org/jira/browse/SPARK-18441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15670210#comment-15670210 ] Nick Pentreath commented on SPARK-18441: Yes, it would be good to understand what this is all about. Perhaps some techniques for dealing with class imbalance could live within Spark. However, take a look at https://github.com/scikit-learn-contrib/imbalanced-learn for example - there is a contrib module focused on class imbalance. Something similar would be very interesting as a package. > Add Smote in spark mlib and ml > -- > > Key: SPARK-18441 > URL: https://issues.apache.org/jira/browse/SPARK-18441 > Project: Spark > Issue Type: Wish > Components: ML, MLlib >Affects Versions: 2.0.1 >Reporter: lichenglin > > PLZ Add Smote in spark mlib and ml in case of the "not balance of train > data" for Classification -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

If you have modified the code, please ensure it's still in the package org.apache.spark..., since BLAS is with modifier private[spark].

May I ask what version of spark this Smote use. I'm using spark2.0.1. But some error occur because of the "org.apache.spark.ml.linalg.BLAS" my eclipse can't recognize this class. > Add Smote in spark mlib and ml > -- > > Key: SPARK-18441 > URL: https://issues.apache.org/jira/browse/SPARK-18441 > Project: Spark > Issue Type: Wish > Components: ML, MLlib >Affects Versions: 2.0.1 >Reporter: lichenglin > > PLZ Add Smote in spark mlib and ml in case of the "not balance of train > data" for Classification -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

[ https://issues.apache.org/jira/browse/SPARK-18441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15666539#comment-15666539 ] yuhao yang commented on SPARK-18441: Hi [~licl], I had an implementation of Smote at https://github.com/hhbyyh/Test/blob/master/Smote/src/SmoteTest.scala . Hope it can help you. Right now Spark 2.1 is already in the QA phase (feature lock down), so the earliest possible window would be 2.2. Before that, we need to resolve some issues, like if SmoteSampler is a feature transformer, we need to find a way to disable it in the pipeline during the predict phase. Besides, guess we need to collect more opinions from the community to see if this is a common requirement. > Add Smote in spark mlib and ml > -- > > Key: SPARK-18441 > URL: https://issues.apache.org/jira/browse/SPARK-18441 > Project: Spark > Issue Type: Wish > Components: ML, MLlib >Affects Versions: 2.0.1 >Reporter: lichenglin > > PLZ Add Smote in spark mlib and ml in case of the "not balance of train > data" for Classification -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
