Classification in MLlib

MLlib also offers a wide range of classifiers; it provides both binomial and multinomial logistic regressor. The decision tree classifier, random forest classifier, gradient-boosted tree classifier, multilayered perceptron classifier, linear support vector machine classifier, and Naive Bayes classifier are supported. Each of them is defined in its class; for details, refer to https://spark.apache.org/docs/2.2.0/ml-classification-regression.html. The basic steps remain the same as we learned in the case of regression; the only difference is now, instead of RMSE or r2 metrics, the models are evaluated on accuracy.
