Mastering Machine Learning on AWS

By: Dr. Saket S.R. Mengle, Maximo Gurmendez

Overview of this book

Amazon Web Services (AWS) is constantly driving new innovations that empower data scientists to explore a variety of machine learning (ML) cloud services. This book is your comprehensive reference for learning and implementing advanced ML algorithms in AWS cloud. As you go through the chapters, you’ll gain insights into how these algorithms can be trained, tuned, and deployed in AWS using Apache Spark on Elastic Map Reduce (EMR), SageMaker, and TensorFlow. While you focus on algorithms such as XGBoost, linear models, factorization machines, and deep nets, the book will also provide you with an overview of AWS as well as detailed practical applications that will help you solve real-world problems. Every application includes a series of companion notebooks with all the necessary code to run on AWS. In the next few chapters, you will learn to use SageMaker and EMR Notebooks to perform a range of tasks, right from smart analytics and predictive modeling through to sentiment analysis. By the end of this book, you will be equipped with the skills you need to effectively handle machine learning projects and implement and evaluate algorithms on AWS.

Implementing linear regression through SageMaker's Linear Learner

Another alternative within AWS for training regression models is to use SageMaker's API to build linear models. In the previous chapter, we explained the basics of this service when we considered how to use BlazingText for our text classification problem. Similarly, we will use Linear Learners in this section and go through the same process, which basically entails three steps:

  1. Stage the training and testing data in S3
  2. Invoke the API to train the model
  3. Use the model to obtain predictions

Unlike what we did in Chapter 2, Classifying Twitter Feeds with Naive Bayes, instead of deploying an endpoint (that is, a web service) to obtain predictions, we will use a batch transformer, which is a service that's capable of obtaining bulk predictions given a model and some data in S3. Let's take a look...
