+#### Linear Support Vector Machine (SVM) Classifier
+
+[Linear Support Vector Machine
(SVM)](https://en.wikipedia.org/wiki/Support_vector_machine#Linear_SVM)
classifier is an SVM classifier with linear kernel.
+This is a binary classifier. Multi-class classification can be achieved by
one-vs-the-rest strategy. We use a simple example to show how to use
`spark.svmLinear`

moment (existing JIRA or design still open), so perhaps it's best we don't
reference that here
