WebSupport Vector Machine (SVM) with Spark 2.0 In this recipe, we use Spark's RDD-based SVM API SVMWithSGD with SGD to classify the population into two binary classes, and then use count and BinaryClassificationMetrics to look at model performance. WebTrain a SVM model given an RDD of (label, features) pairs. We run a fixed number of iterations of gradient descent using a step size of 1.0. We use the entire data set to update the gradient in each iteration.
