Solving regression problems with Gradient Boosted Trees (GBT) in Spark 2.0

This recipe is similar to the GBT classification problem, but we will use regression instead. We will use BoostingStrategy.defaultParams() to direct the GBT to use regression:

algo = "Regression"
val boostingStrategy = BoostingStrategy.defaultParams(algo)

How to do it...

Start a new project in IntelliJ or in an IDE of your choice. Make sure the necessary JAR files are included.

Set up the package location where the program will reside:

package spark.ml.cookbook.chapter10.

Import the necessary packages for the Spark context:

import org.apache.spark.mllib.evaluation.RegressionMetrics
import org.apache.spark.mllib.linalg.Vectors...
