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.

Naive Bayes – pros and cons

In this section, we present the advantages and disadvantages in selecting the Naive Bayes algorithm for classification problems.

These are the pros:

  • Training time: The Naive Bayes algorithm only requires one pass on the entire dataset to calculate the posterior probabilities for each value of the feature in the dataset. So, when we are dealing with large datasets or low-budget hardware, the Naive Bayes algorithm is a feasible choice for most data scientists.

  • Prediction time: Since all the probabilities are pre-computed in the Naive Bayes algorithm, the prediction time of this algorithm is very efficient.

  • Transparency: Since the predictions of Naive Bayes algorithms are based on the posterior probability of each conditional feature, it is easy to understand which features are influencing the predictions. This helps users to understand the...
