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.

Pros and cons of linear models

Regression models are very popular in machine learning and are widely applied in many areas. Linear regression's main advantage is the simplicity of representing the dataset as a simple linear model. Hence, the training time for linear regression is fast. Similarly, the model can be inspected by data scientists to understand which variable is contributing to the decisions of the overall model. Linear regression is recommended in cases where the problem statement is simple and few variables are used for predictions. As the complexity of the dataset increases, linear regression may generate significant errors if the data has a lot of noise in it.

Linear regression makes a bold assumption that the dependent variable has a linear relationship with the regressors. If this does not hold true, then the linear regression algorithm may not be able to...
