  • About one in five people suffer from a psychiatric disorder, and many go years without treatment, if they receive it at all.
  • In a new study, researchers developed machine-learning algorithms that analyzed the relationship between psychiatric disorders and Facebook messages.
  • The algorithms were able to correctly predict the diagnosis of psychiatric disorders with statistical accuracy, suggesting digital tools may someday help clinicians identify mental illnesses in early stages.

  • Artificial intelligence that's smarter than us could potentially solve problems beyond our grasp.
  • AI that are self-learning can absorb whatever information they need from the internet, a Pandora's Box if ever there was one.
  • The nature of computing itself prevents us from limiting the actions of a super-intelligent AI if it gets out of control.

  • If consolidating memories as we sleep is like machine learning, maybe dreams keep our "algorithms" on track.
  • Machine learning is optimized by the injection of a certain amount of nonsense data.
  • Maybe dreams are just weird enough to do the same for us as we sleep.
