It's curious how Man does these things naturally, but needs many man-years of studies and experimentation to arrive at gross approximations of how we function.

It's curious how Man does these things naturally, but needs many man-years of studies and experimentation to arrive at gross approximations of how we function.
All the logic of how we move in crowds is in our brains, we apply it every day. Yet we don't know it explicitly. Something that we do consciously, even.
But, in this case, it's rather emergent behaviour that's pointed out. We know how we behave how the person in front of us steps out of line: we move to the side ourselves or slow down. What's less obvious is when and how this cascades onto the whole crowd.
I don't know exactly what their physical analogies with fluid dynamics are, but this sounds like turbulence.

- optimalsolver 2y agoI often wonder how we impart this kind of knowledge to AI. Imagine someone steps into a subway carriage with only one other passenger in it. They're not likely to sit directly beside or opposite the other person. Would a robot follow this kind of etiquette? I suppose if you emphasize personal space in the training data, but would the developers realize they need to do that?
- _ink_ 2y ago> Would a robot follow this kind of etiquette? If you train it on CCTV footage from inside of subway carriages: yes, I suppose.
- Loughla 2y agoI mean, that actually is A good point about training data. There is more publicly available data of people acting weird than acting normal. We don't usually upload videos of people just existing. Will robots be super awkward and/or aggressive?
- mrastro 2y agoNo, we pay far more attention to people acting weirdly because it's interesting. 99% of CCTV footage will be uneventful and normal.
- neilv 2y agoMaybe one of the reasons it took so long is that MIT orientation included the directive that you're supposed to walk on the right-hand side in hallways. Otherwise, a mathematician could've just perched on Infinite Corridor's overhead vantages for a week, to come to recognize the natural patterns. :)
