> You're going to need a lot of film. Good luck picking the controls for that that ensure your ML system picks up on subtle differences in humans that are lying and not glaringly obvious differences in appearance, accent and even background noise between the footage of the convicts and the control group... I assume you would isolate the people in pre-processing, and do feature extraction of things you might think are interested in. Yes, it'd still require a lot of data, but that data may exist somewhere. A lot of these things are filmed.

If anybody had working lie detecting AI, border control pilot in Greece and Hungary (as per TFA) is the last place you'd see it used. From CIA, and TSA, to your local police department, everybody would have jumped all over it. This is some vendor managing to sell some BS to bureaucrats (probably with the required bribes).

  > From CIA, and TSA, to your local police department, everybody would have jumped all over it. If CIA had it, you wouldn't hear about it. I don't see any reason why these countries couldn't pilot it for their border security before TSA, though. FWIW, polygraphs are still used for security clearance screening. So, they are at least accurate enough for that use. They get a bad rep because they aren't admissible in court, but it's not like they have zero correlation to truth telling. They are still quite accurate.
