Amazon Machine Learning
An Introduction
About the Book
Would you like to perform machine learning without setting up any infrastructure? Amazon Machine Learning (AML) lets you do supervised learning against datasets in S3, RDS and Redshift and build models that can be accessed via realtime or batch predictions. In this book I'll cover how to get your data up to Amazon, how to build your model and how to use your model. We'll also cover areas where AML might not be a good fit, and how to access your model via the API.
