Distributed Machine Learning Concepts
Distributed Machine Learning Demonstration
The course is part of these learning paths
This training course begins with an introduction to the concepts of Distributed Machine Learning. We'll discuss the reasons as to why and when you should consider training your machine learning model within a distributed environment.
We’ll introduce you to Apache Spark and how it can be used to perform machine learning both at scale and speed. Apache Spark is an open-source cluster-computing framework.
Amazon Elastic Map Reduce
We’ll introduce you to Amazon’s Elastic MapReduce service, or EMR for short. EMR provides a managed Hadoop framework that makes it easy, fast, and cost-effective to process vast amounts of data. EMR can be easily configured to host Apache Spark.
We’ll introduce you to MLlib which is Spark’s machine learning module. We’ll discuss how MLlib can be used to perform various machine learning tasks. For this course, we'll focus our attention on decision trees as a machine learning method which the MLlib module supports. A decision tree is a type of supervised machine learning algorithm used often for classification problems.
We’ll introduce you to AWS Glue. AWS Glue is a fully managed extract, transform, and load service, ETL for short. We’ll show you how AWS Glue can be used to prepare our datasets before they are used to train our machine learning models.
Finally, we’ll show you how to use each of the aforementioned services together to launch an EMR cluster configured and pre-installed with Apache Spark for the purpose of training a machine learning model using a decision tree. This demonstration will provide an end-to-end solution that provides machine learning predictive capabilities.
The intended audience for this course includes:
- Data scientists and/or data analysts
- Anyone interested in learning and performing distributed machine learning, or machine learning at scale
- Anyone with an interest in Apache Spark and/or Amazon Elastic MapReduce
By completing this course, you will:
- Understand what Distributed machine learning is and what it offers
- Understand the benefits of Apache Spark and Elastic MapReduce
- Understand Spark MLlib as machine learning framework
- Create your own distributed machine learning environment consisting of Apache Spark, MLlib, and Elastic MapReduce.
- Understand how to use AWS Glue to perform ETL on your datasets in preparation for training a your machine learning model
- Know how to operate and execute a Zeppelin notebook, resulting in job submission to your Spark cluster
- Understand what a machine learning Decision Tree is and how to code one using MLlib
The following prerequisites will be both useful and helpful for this course:
- A background in statistics or probability
- Basic understanding of data analytics
- General development and coding experience
- AWS VPC networking and IAM security experience (for the demonstrations)
The agenda for the remainder of this course is as follows:
- We’ll discuss what Distributed Machine Learning is and when and why you might consider using it
- We’ll review the Apache Spark application, and its MLlib machine learning module
- We’ll review the Elastic MapReduce service
- We’ll provide an understanding what a Decision Tree is - and what types of analytical problems it is suited towards
- We’ll review the basics of using Apache Zeppelin notebooks - which can be used for interactive machine learning sessions
- We’ll review AWS Glue. We’ll show you how you can use AWS Glue to perform ETL to prepare our datasets for ingestion into a machine learning pipeline.
- Finally - We’ll present a demonstration of a fully functional distributed machine learning environment implemented using Spark running on top of an EMR cluster

Welcome back. In this lecture, we'll begin discussing what exactly distributed machine learning is. We discuss what motivations may exist that could require you to consider a distributed machine learning environment. Distributed machine learning refers to the concept in which machine learning processes have been scaled out and deployed across a cluster of compute resources. In doing so, distributed machine learning allows you to draw upon more compute resource, allowing you to paralyze the machine learning mechanics and mathematical operations, which in turn, expediates end results and outputs.
So what exactly might motivate you, and your business requirements into justifying a distributed machine learning architecture? Let's cover off some of the possible reasons.
- Large datasets. Some datasets, for example, petabyte-scale datasets, are just too big to be processed by a single machine.
- Speed. A distributed machine learning environment affords you the ability to paralyze your machine learning processing requirements, allowing you to achieve quicker results comparatively to running the same processing on a single node environment.
- Complexity. The complexity of the dataset in terms of its features in the particular machine learning algorithm may exceed the capabilities of a single node setup.
- And accuracy. The accuracy of a machine learning model can be enhanced by processing more data. This, in turn, is connected back to the large datasets point above.
- In summary, distributed machine learning is an important technique given the amount of data being generated in today's big data era. Leading on from this, the question is, which platform might we choose to help build out a distributed machine learning environment? One such platform that has become very popular in recent times is Apache Spark.
As we'll see in the next lecture, Apache Spark is a specialized platform which excels at performing distributed computation and in more specialized cases, distributed machine learning. That concludes this lecture. Go ahead and close this and we'll see you shortly in the next lecture, where we'll introduce you to Apache Spark, a lightning-fast cluster computing engine, perfect for distributed machine learning.
