Robot Learning To Recognize Itself In Mirror 133

First time accepted submitter Thorodin writes in with a story at the BBC about scientists at Yale who have built a robot that they hope will be able to recognize itself in a mirror. "A robot named Nico could soon pass a landmark test - recognizing itself in a mirror. Such self-awareness would represent a step towards the ultimate goal of thinking robots. Nico, developed by computer scientists at Yale University, will take the test in the coming months. The ultimate aim is for Nico to use a mirror to interpret objects around it, in the same way as humans use a rear-view mirror to look for cars. 'It is a spatial reasoning task for the robot to understand that its arm is on it not on the other side of the mirror,' Justin Hart, the PhD student leading the research told BBC News. So far the robot has been programmed to recognize a reflection of its arm, but ultimately Mr Hart wants it to pass the "full mirror test". The so-called mirror test was originally developed in 1970 and has become the classic test of self-awareness."

      Actually, it's more about recognising the auto-motion structure in the scene. I'm familiar with Justin's work (Go Team Scazlab!) and it's a lot deeper and more interesting than the article gives it credit for.

      AI claims from the 70s ruined a generation of people for machine intelligence (which is why we now have to sell it as 'machine intelligence' or 'machine learning'). Knowing what part of the camera scene is moving because something is happening, and knowing what part of the scene is moving because you're waving your end-effector is useful. If you can extract your own state from indicators in the environment, then you have more information to work with - that's why we use a mirror to do our hair and straighten our ties.

        I actually prefer the term Machine Intelligence to Artificial Intelligence. There is nothing artificial about a neural network's intelligence. The network may be artificial (man made, or existing as a simulation), but the degree of intelligence is not artificial; It's a function of the network's complexity. Intelligence emerges due to the properties complex interactions naturally have.

        Cars do not create Artificial Movement. Machine Learning does not create Artificial Knowledge. Machine Intelligence does not provide Artificial Intelligence, it simply yields a measure of intelligence. A house fly, dog, or penguin doesn't have as complex a neural network as you likely do, but this does not make them Artificially Intelligent simply because their degree of intellect and awareness is less than your own. When we train the lesser minds to communicate with us, and perform tasks, they are not artificially performing the tasks.

        I find the term A.I. to be racist, and indicative of the chauvinistic attitude some humans have about their own mental prowess -- Your brains are not special. Any sufficiently complex interaction is indistinguishable from sentience, because that IS what sentience is. Once cybernetic systems attain (and surpass) the level of complexity present in humans brains, Artificial Intelligence will be a derogatory term: "Oh you pass yourself off as being smart, but you're just Artificially Intelligent -- You don't actually understand anything!"

        Also: Not that it matters, but I don't personally believe that a god created the race of men. However, some do consider this to be true, and yet they do not call themselves Artificial Life...

          First of all, thats a pretty horrible misuse of the term "racist", and second, the term "artificial" means, by definition, created through art (art here being the broad sense as any product of human activity, rather than the fine arts): i.e. created by human intention and design. By definition "Machine Intelligence" is "Artificial Intelligence", at least so far as we have created it. That intelligence is designed and a product of human work. It's intended, and is brought about not because of some emergent behavior found naturally in existence, but because humans arranged it that way and brought it about. That's not in any way racist, it's just the meaning of the words.

          It would be completely irrational and contradictory to the very meaning of the term to call humans "artificial life", since we were not created by human art. You'd destroy the meaning of the words to call humans "artificial", just as we wouldn't call the sun "artificial" even if you said it was created by a god, since that's not what the word means. Long story short, you are trying to destroy the meaning of words. Don't do that: it's bad for everyone.

          • Note that part of the problem in the discussion here is that the word "artificial" has several meanings. The grandparent is referring to one meaning which is something like "contrived or false", while the parent is referring to a related meaning which is "made or produced by human beings rather than occurring naturally, typically as a copy of something natural". I think both of these meanings of artificial are in play when we talk about AI, although the meaning used by the parent is probably the more fittin

          Precisely, further, "intelligence" is in the eye of the beholder. My favorite example is an ants nest, each individual ant follows some very simple rules, so simple it doesn't need a brain to carry them out, it's nervous system alone provides enough "intelligence". The ant and the neuron both display automata like behavior that can be expressed as a state machine. Ants and neurons live in colonies (nests and brains), unlike the individuals the colonies do display what most people would call "intelligent behavior", yet nests and brains are also just state machines all the way down.

          Your brains are not special.

          My brain uses it's knowledge to inform itself that it will cease to exist, but deep down in the brain stem it's not really buying it's own story. And it's certainly not buying the idea it's not unique or special. I think programmers can see the idea that the human brain could be expressed as a state machine more readily than most because they are in the business of producing intelligent behavior from simple rules. However don't underestimate the impact that a deeply rooted acceptance of ones own morality can have [youtube.com] (meat starts @ 3:55), non-existence is a fear that comes from the brain stem, it's the emotional driver for the "fight or flight" response. All humans recoil instinctively from the idea like ants instinctively find the sugar bowl. The existential question can be a deep dark rabbit hole with some side routes leading to depression and insanity. Of course if you can avoid (or get past ) all that, you may eventually lose the fear of not knowing [youtube.com], the moment of genuine acceptance is an experience many have described as "religious" - as in the natural buzz one gets from surviving "a leap of faith".

He fixed my broken watch, it didn't matter that he did it by staring at the TV with a face like a constipation sufferer, the proof was right there, the watch ran for days!!! A couple of years later I had a book shelf jammed full of "alternative science". James Randi set me straight on the real meaning of skepticism in his (short) 1980 book debunking Geller (that's HS science for you, both then and now), ironically I had picked up Randi's book from the bargain bin because I thought I knew enough to easily debunk it, in one night he had convincingly debunked my entire bookshelf.

          • Nice post. While neurons display some behaviors that can be characterized using a state machine, they display plenty more behaviors that have not, and probably cannot, be characterized as such. A contrast-response function can be measured for a neuron in the visual system, but that is not a full explanation of its behavior or its complexity. The same is true of humans. A human taking a vision test with an eye chart can be modeled with a state machine, but it doesn't mean the human is a state machine followi

Even machines that are programed to process new data into existing algorythms for feedback processing are **still** doing that 'learning' according to a human-programed way of processing and integrating data...its all just machines executing complex instructions at the core!

    Commander Data...some people contextualize "thinking robots" as a technical level at which a machine is so like beings with Sapience that it is immoral to deny them the rights of a humanoid. This is science fiction. It is helpful, but it is a scenario based in a world with several assumptions. Its not fit to apply to computing directly. We do not know how the human mind ultimately works...unless we have that, then there is nothing to accurately compare a non-human brain to consistently.

    Ultimately, if neuroscience and AI converge, meaning we can map every thought in the human brain **AND** have the technical ability to construct an artificial system that enables what we know as 'free will' and 'thought' and 'choice' and especially 'self awareness'....THEN and ONLY THEN have we made something...

        That's assuming that the human brain is a Turing machine - as far as I'm aware no one has proven that *all* conceivable computation engines are equivalent to a Turing variation, and in fact the very fact that there are non-equivalent variations on the Turing machine is evidence that we've found limitations in the original concept, and one can only assume there are additional yet-undiscovered limitations.

        Not that I think machine intelligence is impossible, but I seriously doubt it will be human-like beyond w

      • Also Turing equivalence says an electronic computer should be able to do anything that a human brain can.

        No it doesn't. It says that any electronic computer that can be shown to be equivalent to the theoretical Turing machine can solve any problem that it is possible to solve analytically using an algorithm (and also defines lots of problems that can't be solved that way).

        A Turing machine can't even generate a random number - just the next term in a well-defined, but complex, number series that is totally deterministic. You can attach a 'true' random number generator (i.e. that uses some physical process lik

        • AFAIK, the best current guess is that the brain is a neural net, not a Turing machine. Neural nets are not Turing machines and do not solve problems analytically using algorithms - they produce "best guess" solutions based on a network of connections and probabilistic processes, usually developed by 'learning'. They can 'solve' ill-defined or uncomputable problems in the sense that they produce a very reliable guess: you don't actually solve a differential equation every time you catch a ball.

          Are you sure that neural nets are not turing machines? I mean, if that is true it would mean that there is no way of implementing a neural network; if this is the case then what exactly is it that is not implementable? "best guess" solutions are generally done by statistical analysis, which I know is not currently on par with the human brain. But again, if there is some innate property to the "best guess" functionality of the human brain that is not implementable, what would that be?

          Here's me guessing that "Self-awareness" is not a computable problem...

          I kind of agree with you

          • Are you sure that neural nets are not turing machines? I mean, if that is true it would mean that there is no way of implementing* a neural network;

            You can implement a neural net physically (the whole point is that they're meant to be models of how biological systems work) and, of course, most neural network research is done by simulating the networks on a computer... but if you actually built the network out analogue electronics or "wetware" then there's no absolute guarantee that it would work the same way as the simulation. It might work - it could be very accurate - but you don't get the "Turing Promise" that you algorithm will behave identically r

      • Others in this thread have responded to 'gronofer' very well....interesting stuff...

        I just have a side note to add: The way some irrationally apply Turing reminds me of the Clovis Dogma [wikipedia.org] that continues to be a bugaboo for people trying to do real science.

    • "Ultimately, if neuroscience and AI converge, meaning we can map every thought in the human brain **AND** have the technical ability to construct an artificial system that enables what we know as 'free will' and 'thought' and 'choice' and especially 'self awareness'....THEN and ONLY THEN have we made something..." Ha, try putting that on an application for funding.

        I love it....thanks for your comment...its funny b/c its true.

        I used to work in Academia and the fact is, the truth of your joke has caused me much grief over the years. I do not want to set off some sort of grenade in the AI/Cybernetics/Computer Science fields or something like that...I want them to get shit-tons of funding...just for different research!

        I love going over the literature on robotics and keeping up in the popular press. I think we should keep making faster, bigger/smaller, better, etc. techno

    So now robots can do what pigeons can do. Self-awareness is a hypothetical construct http://psychclassics.yorku.ca/Skinner/Theories/ [yorku.ca] which may not be very useful.

  • Show it a picture of itself: "Self!"

    Build another one and show it that: "Self!"

    Pattern recognition is not self awareness.

  • Just put unique identifiers on the bot, like colored reflectors, in horizontal sequence. Then you can tell if it's another bot, or your own bot in the mirror. The real trick is to take a random object, with no unique identifiers, and classify it. beep beep - that's a bird - beep beep...
