I went camping in the alps once. On our last night, my friend took a bowl and gathered ashes from the campfire. Half ritualistic, half jokingly, she said that those ashes mark our trek and experiences, that she would carry the ashes back home no matter what.
I was very confused how she would pass a bowl of unidentified ash from the airport security (we only had a backpack each). She drafted a poorly done and obviously fake death certificate. It was not campfire ash anymore, it was the remains of her father.
The people at the airport were visibly awkward, they tried to be as accommodating as they could. She flew back home with a plastic bowl of ashes from our campfire, it even had some parts of birch and branches.
Airport security was easily fooled. And the author's mom is easily fooled too, motherly instincts be damned. Would a neural net be fooled by the author's attempts? I know for sure that an automated security system would sound the alarm on my friend. I 'd like to see adversarial networks fighting each other on such premises. A son network trying to fool the mother network and vice versa ad infinitum, at least 1 billion of simulation hours in. What kind of wonders would come out
- gabcoh 8y agoI agree that in the short term adversarial neural networks may be a good line of defense against machine fabricated audio and video, but in the long term it’s a loosing battle. Eventually the neural networks producing the audio and video will become pixel perfect and at that point no neural network would be able to detect the manipulation. I think we need to seek out a different, more future proof solution to the problem.

- taneq 8y agoI think 'fooled' might be the wrong word to describe the airport security staff. "Had to make a judgement call and decided to err on the side of lenience" is probably a fairer description.
- babkayaga 8y agoWhy would ashes be forbidden on an airplane?

- informatimago 8y agoI can see easily half a dozen problems you can wreak havoc with with ashes on an airplane. Ashes or any dust, actually. Remember, it's essentially a closed, hermetic, environment.
- VBprogrammer 8y agoPeople have this idea that air on an airplane is constantly being recycled. I'm guessing that is where your objection comes from. In reality the engines are constantly producing a stream of hot compressed air which is bleed off for various subsystems. One of these is the air conditioning systems. These cool that air and filter it so that it's clean and at a reasonable temperature for passenger comfort. The air is added to the cabin at a pretty much fixed rate and the pressure is regulated by a dump valve which dumps excess pressure overboard. There is no real recycling of air.
- MajorSauce 8y agoI'm genuinely curious, How do they regulate oxygen levels? Or are those levels more or less the same as on the ground but it's the pressure that incommodes?
- MisterTea 8y agoThe pressure changes with altitude, not the gas makeup. So at 35kft/10.6km the air is still 21% oxygen. The gp is right, the engines bleed off some of the fresh air from the compressor stages in the engine, before the combustion stage, and use that to supply the cabin. This is called Bleed Air - https://en.wikipedia.org/wiki/Bleed_air https://en.wikipedia.org/wiki/Bleed_air
