TfL's AI Tube Station experiment is amazing and slightly terrifying

Very interesting!

>> My favourite thing from the TfL docs though is on the attempts by the AI to spot “aggressive behaviour”. Unfortunately for reasons TfL redacted from the documents, there was insufficient training data to make this reliable (what would this even look like?).

>> So TfL hit upon a novel solution: They instead trained the system to spot people with both arms raised in the air – because this is thought to be a “common behaviour” linked to acts of aggression (presumably raised fists or ‘hands up’ as a surrender-like gesture).

Luckily no real incidents of this nature during the trial.

Tbh given how much of a Wild West tube stations are at peak times I’d welcome something a bit more aggressive and actively monitored

Slippery slope I know
