The past couple of days, I read a couple of long articles about some issues surrounding machine learning:¹

• The Dark Secret at the Heart of AI. “No one really knows how the most advanced algorithms do what they do. That could be a problem.” From MIT Technology Review.
• Alien Knowledge — When Machines Justify Knowledge. I like the original title better: “Our machines now have knowledge we’ll never understand.”
• Elon Musk’s Billion-Dollar Crusade to Stop the A.I. Apocalypse. “You’d think that anytime Musk, Stephen Hawking, and Bill Gates are all raising the same warning about A.I.–as all of them are–it would be a 10-alarm fire.”

Recommended.

Update. Before you assume I think machine learning is all doom and gloom, rest assured. I don’t.

• Can machine-learning improve cardiovascular risk prediction using routine clinical data? This is one example of where Betteridge’s law of headlines fails.
