So far in this book, we've examined the exciting history of healthcare analytics and some of the ways it currently impacts our healthcare system. In this chapter, we provide a sense of the latest developments in the field and what will likely be coming to healthcare analytics in the not-so-distant future. We'll delve into healthcare and the internet, specifically the Internet of Things (IoT) and social media applications, to see how they are playing roles in improving health. Next, we'll take a look at some of the new algorithms (collectively referred to as "deep learning") that are achieving state-of-the-art performance in medical prediction tasks. Finally, although this book has presented the state of healthcare analytics in a hopeful and optimistic fashion, there are still some considerable obstacles and barriers that must be overcome for healthcare analytics to disruptively impact our healthcare system for the better. We'll discuss those at the end of the book.
