Applied Machine Learning for Healthcare and Life Sciences Using AWS

By: Ujjwal Ratan

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.

Introducing SageMaker Clarify and Model Monitor

SageMaker Clarify provides you with greater visibility into your data and the model it is used to train. Before we begin using a dataset for training, it is important to understand whether there is any bias in the dataset. A biased dataset can influence the prediction behavior of the model. For instance, if a model is trained on a dataset that only has records for older individuals, it will be less accurate when applied to predict outcomes for younger individuals. SageMaker Clarify also allows you to explain your model by showing you reports of which attributes are influencing the model’s prediction behavior. Once the model is deployed, it needs to be monitored for changes in behavior over time as real-world data changes. This is done using SageMaker Model Monitor, which alerts you if there is a shift in the feature importance in the real-world data.

Let us now look at SageMaker Clarify and Model Monitor in more detail.
