AI and health: Using machine learning to understand the human immune system

Machine learning, task automation and robotics are already widely used in business. These and other AI technologies are about to multiply, and we look at how organizations can best take advantage of them. Think of your immune response as a giant machine-learning problem, with your body as the computer. Immune cells travel around your body, sampling all sorts of matter they come into contact with, from your own cells to the cells of organisms that definitely shouldn't be there. If immune cells encounter something they know shouldn't part of your body -- bacteria or a virus, say -- the body scales up the cells that know how to deal with that interloper.
