Overview of this book

R provides excellent visualization features that are essential for exploring data before using it in automated learning. Applied Supervised Learning with R helps you cover the complete process of employing R to develop applications using supervised machine learning algorithms for your business needs. The book starts by helping you develop your analytical thinking to create a problem statement using business inputs and domain research. You will then learn different evaluation metrics that compare various algorithms, and later progress to using these metrics to select the best algorithm for your problem. After finalizing the algorithm you want to use, you will study the hyperparameter optimization technique to fine-tune your set of optimal parameters. The book demonstrates how you can add different regularization terms to avoid overfitting your model. By the end of this book, you will have gained the advanced skills you need for modeling a supervised machine learning algorithm that precisely fulfills your business needs.

Preface

What is Amazon Lambda?


AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. The service enables us to develop serverless applications. The term serverless indicates that we do not actually need to manage and provision the infrastructure resources; instead, they are managed by the cloud service provider, and we only pay for what we use, say, pay per event or execution. AWS Lambda can be configured to execute a defined function in response to a specific event, say, when someone uploads a new file to a defined S3 bucket or invokes another function or another service in AWS.
