Exercises

  1. Revisit the classification problem in Chapter 6, Bayesian Classification Models. Repeat the same problem using the glm() function of SparkR.

  2. Revisit the linear regression problem, we did in this chapter, using SparkR. After creating the AWS instance, repeat this problem using RStudio server on AWS.
