AI-Powered Body Scanners Could Soon Speed Up Your Airport Check-in (theguardian.com) 111

Posted by msmash from the no-waiting-lines dept.
An anonymous reader shares a report on the Guardian:A startup bankrolled by Bill Gates is about to conduct the first public trials of high-speed body scanners powered by artificial intelligence (AI), the Guardian can reveal. According to documents filed with the US Federal Communications Commission (FCC), Boston-based Evolv Technology is planning to test its system at Union Station in Washington DC, in Los Angeles's Union Station metro and at Denver international airport. Evolv uses the same millimetre-wave radio frequencies as the controversial, and painfully slow, body scanners now found at many airport security checkpoints. However, the new device can complete its scan in a fraction of second, using computer vision and machine learning to spot guns and bombs. This means passengers can simply walk through a scanning gate without stopping or even slowing down -- like the hi-tech scanners seen in the 1990 sci-fi film Total Recall. A nearby security guard with a tablet is then shown either an "all-clear" sign, or a photo of the person with suspicious areas highlighted. Evolv says the system can scan 800 people an hour, without anyone having to remove their keys, coins or cellphones.

      There's nothing intelligent about it. It's just fancy pattern-matching

      The problem is that there is no clear-cut definition or dividing line. I've seen long online debates about this, and there are no good lines in the sand yet. All attempts failed key tests offered up, or were too subjective to evaluate well.

      For one, we still don't know enough about how the human brain works such that we cannot say what distinguishes things called "AI" from something as powerful as the human brain. For all we know, the human brain is merely "fancy pattern matching" at a level of fanciness we don't understand yet.

      Some call pattern-matching AI "lossy statistical analysis for the sake of speed/cost".

      I suspect human brains also (typically) use abstract modelling of various sorts where symbols or some kind of ID's with attributes/links/factors are stand-in's for actual people and things to simplify certain cognitive processes. Thus, the human brain may merely be "fancy pattern matching" coordinated with "fancy modelling": statistics + modeling.

      Various known AI techniques use pattern matching and others use modelling, BUT nobody has found a way to coordinate them together in a general-purpose way to reinforce each other (triangulate). It's as if we got all the key parts, but don't know how to put them together right. We don't know how to build central governors to coordinate AI "organs" for common goals.

          ShanghaiBill is right. As humans we're not much more than pattern-matching algorithms with a sensory and mobility package. Most of what our brain does is screen out the deluge of sensory input we're bombarded with as it attempts to make some sense of it.

    • I am so sick of hearing about "Artificial Intelligence". There's nothing intelligent about it.

      This reminds me of a certain Sherlock Holmes passage. Sherlock Holmes deduces all sorts about an individual by having a quick glance at them (as normal). The man is astonished and asks how he knew- when Sherlock explains the man replies that he thought at first he had done something clever, but now realises it wasn't.

      Sherlock Holmes's quick eye took in my occupation, and he shook his head with a smile as he noticed my questioning glances. "Beyond the obvious facts that he has at some time done manual labor, that he takes snuff, that he is a Freemason, that he has been in China, and that he has done a considerable amount of writing lately, I can deduce nothing else."

      Mr. Jabez Wilson started up in his chair, with his forefinger upon the paper, but his eyes upon my companion.

      How, in the name of good fortune, did you know all that, Mr. Holmes?" he asked. "How did you know, for example, that I did manual labor? It's as true as gospel, for I began as a ship's carpenter."

      "Your hands, my dear sir. Your right hand is quite a size larger than your left. You have worked with it and the muscles are more developed."

      "Well, the snuff, then, and the Freemasonry?"

      "I won't insult your intelligence by telling you how I read that, especially as, rather against the strict rules of your order, you use an arc and compass breastpin."

      "Ah, of course, I forgot that. But the writing?"

      "What else can be indicated by that right cuff so very shiny for five inches, and the left one with the smooth patch near the elbow where you rest it upon the desk."

      "Well, but China?"

      "The fish which you have tattooed immediately above your wrist could only have been done in China. I have made a small study of tattoo marks, and have even contributed to the literature of the subject. That trick of staining the fishes' scales of a delicate pink is quite peculiar to China. When, in addition, I see a Chinese coin hanging from your watch chain, the matter becomes even more simple."

      Mr. Jabez Wilson laughed heavily. "Well, I never!" said he. "I thought at first that you had done something clever, but I see that there was nothing in it after all."

      Your claim that Artificial Intelligence doesn't use "Intelligence" is much like Mr. Wilson claiming what Sherlock did wasn't "clever".
