Building Machine Learning Models in Spark 2

by Janani Ravi

Training ML models is a compute-intensive operation and is best done in a distributed environment. This course will teach you how Spark can efficiently perform data explorations, cleaning, aggregations, and train ML models all on one platform.

What you'll learn

Spark is possibly the most popular engine for big data processing these days. In this course, Building Machine Learning Models in Spark 2, you will learn to build and train Machine Learning (ML) models such as regression, classification, clustering, and recommendation systems on Spark 2.x's distributed processing environment.

This course starts off with an introduction of the 2 ML libraries available in Spark 2; the older spark.mllib library built on top of RDDs and the newer spark.ml library built on top of dataframes. You will get to see the two compared to help you know when to pick one over the other.

You will get to see a classification model built using Decision Trees the old way, and see how you can implement the same model on the newer spark.ml library.

The course covers many features of Spark 2, including going over a brand new feature in Spark 2, the ML pipelines used to chain your data transformations and ML operations.

At the end of this course you will be comfortable using the advanced features that Spark 2 offers for machine learning. You'll learn to use components such as Transformers, Estimators, and Parameters within your ML pipelines to work with distributed training at scale.
