Practical Predictive Analytics

About this chapter/what you will learn

In the previous chapters, we introduced Spark and SparkR, with the emphasis on exploring data using SQL. In this chapter, we will begin to look at the machine learning capabilities of Spark using MLlib, which is the native machine learning library which is packaged with Spark.

In this chapter we will cover logistic regression, and clustering algorithms. In the next chapter we will cover rule based algorithm, which include decision trees. Some of the material has already been discussed in prior chapters using PC versions of R. In this chapter, as well as the next, we will focus predominantly on how to prepare your data and apply these techniques using the MLLib algorihms which exist in Spark.
