Joseph K. Bradley commented on SPARK-4638: ------------------------------------------ Commenting here b/c of the recent dev list thread: Non-linear kernels for SVMs in Spark would be great to have. The main barriers are: * Kernelized SVM training is hard to distribute. Naive methods require a lot of communication. To get this feature into Spark, we'd need to do proper background research and write up a good design. * Other ML algorithms are arguably more in demand and still need improvements (as of the date of this comment). Tree ensembles are first-and-foremost in my mind. > Spark's MLlib SVM classification to include Kernels like Gaussian / (RBF) to > find non linear boundaries > ------------------------------------------------------------------------------------------------------- > > Key: SPARK-4638 > URL: https://issues.apache.org/jira/browse/SPARK-4638 > Project: Spark > Issue Type: New Feature > Components: MLlib > Reporter: madankumar s > Labels: Gaussian, Kernels, SVM > Attachments: kernels-1.3.patch > > > SPARK MLlib Classification Module: > Add Kernel functionalities to SVM Classifier to find non linear patterns -- 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
