Can Your Smartphone Read Your Mind?

One oft-cited solution to the big data challenge of digital mental health data is to use artificial intelligence approaches like deep learning to help make sense of the raw data. Deep learning is the art and science of building enormous computer models--neural networks--that can be used to predict, classify, edit, describe, and create videos, images, and text. For example, apps can organize your photos by topic, even if you never labeled them yourself. But analyzing and helping human beings is much more difficult than helping a machine recognize the difference between a selfie and a landscape photo. Artificial intelligence programs still struggle with cancer diagnoses, even when complete medical records are available and even with medical knowledge of that cancer well characterized at the genetic level.
