Overview of this book

While machine learning is not new, it's only now that we are beginning to uncover its true potential in the healthcare and life sciences industry. The availability of real-world datasets and access to better compute resources have helped researchers invent applications that utilize known AI techniques in every segment of this industry, such as providers, payers, drug discovery, and genomics. This book starts by summarizing the introductory concepts of machine learning and AWS machine learning services. You’ll then go through chapters dedicated to each segment of the healthcare and life sciences industry. Each of these chapters has three key purposes -- First, to introduce each segment of the industry, its challenges, and the applications of machine learning relevant to that segment. Second, to help you get to grips with the features of the services available in the AWS machine learning stack like Amazon SageMaker and Amazon Comprehend Medical. Third, to enable you to apply your new skills to create an ML-driven solution to solve problems particular to that segment. The concluding chapters outline future industry trends and applications. By the end of this book, you’ll be aware of key challenges faced in applying AI to healthcare and life sciences industry and learn how to address those challenges with confidence.

Building a medical image classification model using SageMaker

One common application of ML in medical imaging is for classifying images into different categories. These categories can consist of different types of diseases determined by visual biomarkers. It can also recognize anomalies in a broad group of images and flag the ones that need further investigation by a radiologist. Having a classifier automate the task of prescreening the images reduces the burden on radiologists, who can concentrate on more complex and nuanced cases requiring expert intervention. In this exercise, we will train a model on SageMaker to recognize signs of pneumonia in a chest X-ray. Let us begin by acquiring the dataset.

Acquiring the dataset and code

The Chest X-Ray Images (Pneumonia) dataset is available on the Kaggle website here: https://www.kaggle.com/datasets/paultimothymooney/chest-xray-pneumonia?resource=download.

The dataset consists of 5,863 chest X-ray images in JPEG format organized...
