[jira] [Commented] (MADLIB-938) Non-linear SVM - polynomial kernel

    [ https://issues.apache.org/jira/browse/MADLIB-938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15158402#comment-15158402 ]

    SVM: Add Polynomial Kernel

    JIRA: MADLIB-938
    
    The features are transformed using Kar and Karnick's appoach, which applies to any positive definite
    kernel where the kernel function admits a Maclaurin expansion. This commit implements the special case
    when the kernel function is polynomial.
