We all know remarkably little about how AI language models work

AI language models are usually not humans, and yet we evaluate them as in the event that they were, using tests just like the bar exam or the US Medical Licensing Examination.

The models are inclined to do very well in these exams, probably because examples of such exams are abundant within the models’ training data. As my colleague Will Douglas Heaven writes in his most up-to-date article, “some individuals are dazzled by what they see as glimmers of human-like intelligence; others aren’t convinced one bit.” 

A growing variety of experts have called for these tests to be ditched, saying they boost AI hype and create “the illusion that [AI language models] have greater capabilities than what truly exists.” Read the total story here. 

What stood out to me in Will’s story is that we all know remarkably little about how AI language models work and why they generate the things they do. With these tests, we’re attempting to measure and glorify their “intelligence” based on their outputs, without fully understanding how they function under the hood. 

Other highlights:

Our tendency to anthropomorphize makes this messy: “People have been giving human intelligence tests—IQ tests and so forth—to machines for the reason that very starting of AI,” says Melanie Mitchell, an artificial-intelligence researcher on the Santa Fe Institute in Recent Mexico. “The problem throughout has been what it means while you test a machine like this. It doesn’t mean the identical thing that it means for a human.”

Kids vs. GPT-3: Researchers on the University of California, Los Angeles, gave GPT-3 a story a few magical genie transferring jewels between two bottles after which asked it the right way to transfer gumballs from one bowl to a different, using objects resembling a posterboard and a cardboard tube. The thought is that the story hints at ways to resolve the issue. GPT-3 proposed elaborate but mechanically nonsensical solutions. “That is the kind of thing that children can easily solve,” says Taylor Webb, one in every of the researchers. 

AI language models are usually not humans: “With large language models producing text that seems so human-like, it’s tempting to assume that human psychology tests shall be useful for evaluating them. But that’s not true: human psychology tests depend on many assumptions that won’t hold for giant language models,” says Laura Weidinger, a senior research scientist at Google DeepMind. 

Lessons from the animal kingdom: Lucy Cheke, a psychologist on the University of Cambridge, UK, suggests AI researchers could adapt techniques used to review animals, which have been developed to avoid jumping to conclusions based on human bias.

No person knows how language models work: “I believe that the elemental problem is that we keep specializing in test results slightly than the way you pass the tests,” says Tomer Ullman, a cognitive scientist at Harvard University.

Google DeepMind has launched a watermarking tool for AI-generated images

Google DeepMind has launched a brand new watermarking tool that labels whether images have been generated with AI. The tool, called SynthID, will initially be available only to users of Google’s AI image generator Imagen.  Users will give you the option to generate images after which select whether so as to add a watermark or not. The hope is that it could help people tell when AI-generated content is being passed off as real, or protect copyright. 

Baby steps: Google DeepMind is now the primary Big Tech company to publicly launch such a tool, following a voluntary pledge with the White House to develop responsible AI. Watermarking—a method where you hide a signal in a bit of text or a picture to discover it as AI-generated—has turn out to be probably the most popular ideas proposed to curb such harms. It’s a great start, but watermarks alone won’t create more trust online. Read more from me here.
