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.

Understanding how clustering algorithms work

Cluster analysis, or clustering, is a process of grouping a set of observations based on their similarities. The idea is that the observations in a cluster are more similar to one another than the observations from other clusters. Hence, the outcome of this algorithm is a set of clusters that can identify the patterns in the dataset and arrange the data into different clusters.

Clustering algorithms are referred to as unsupervised learning algorithms. Unsupervised learning does not depend on predicting ground truth and is designed to discover the natural patterns in the data. Since there is no ground truth provided, it is difficult to compare different unsupervised learning models. Unsupervised learning is generally used for exploratory analysis and dimensionality reduction. Clustering is an example of exploratory analysis. In this...
