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.

Building a custom chatbot using Amazon Lex

In this section, we will build a simple custom conversational bot using Amazon Lex. To access the Amazon Lex dashboard, simply go to the AWS console and search for this service. Once you reach the dashboard, you will have an option to create a new bot. You can build separate bots that can handle specific tasks. In this example, we provide the following steps to create a bot that the user can ask to order food from a specific restaurant at a specified time:

  1. To get started, click on the Create bot option on the dashboard. You will be able to access a screen that is similar to the following screenshot:

You will have to specify the bot name on this screen and the voice that you want to select when testing the bot. You can also specify when the session times out so that a person who has left the order incomplete and has left their machine...
