What if Your Cellphone Data Can Reveal Whether You Have Alzheimer's?

This is all very promising. Before we can use these new sources of data to inform clinical decision-making, we need to overcome some significant technical challenges. While we have recently seen important advancements in machine learning and artificial intelligence, this work has been largely driven by consumer applications, with Google, IBM, Facebook, Microsoft, and Amazon leading the way. These companies have developed deep learning models that achieve near-human performance on certain tasks, even as their workings are largely incomprehensible to human users. Most people use the Amazon Echo without an understanding of the A.I. algorithms that underlie the speech recognition engine.
