New Object Recognition Algorithm Learns On the Fly 100

Posted by samzenpus from the we'll-do-it-live dept.
Zothecula writes "Scientists at Brigham Young University (BYU) have developed an algorithm that can accurately identify objects in images or videos and can learn to recognize new objects on its own. Although other object recognition systems exist, the Evolution-Constructed Features algorithm is notable in that it decides for itself what features of an object are significant for identifying the object and is able to learn new objects without human intervention."

I assume that rather than have a human input the best guess at what features to look for, like eye spacing/nose placement, they use a Genetic Algorithm to narrow down to a good enough input. Still requires a person to load a bunch of pictures of air planes, and tell it to "learn" these objects. It's not really learning objects on its own, but rather learning which traits are best for identifying the object on its own.

        The way I understand it is that it identifies recurrent features and learns them. Meaning that giving it a huge image library with no labels would mean it can recognize say, roses, but it would call them "object 193131", not "rose".

          There is no way an image-based unsupervised algorithm can learn to recognize objects. "Shapes that frequently go together," yes. But what we consider "objects" is not an objective reality, it is a mental construct that is largely functionally-determined. It will never figure out all the different forms to which we ascribe the label "chair."

          Sitting on a street, a "bicycle" is an object because it is most like to be operated on as a unit. But to a bicycle mechanic, a bicycle is a collection of objects, such as a frame, a seat.. and so on because they need to decompose the "bicycle" construct to do their job. To somebody on an assembly line putting together bicycle seats, a seat is (at least initially) several different objects.

          So, truly unsupervised algorithms cannot do useful recognition - that is, classify objects the same way people do. (A robot that could experiment with its environment and learn to use "objects" could come closer).

            The unsupervised algorithm discussed in the article seems to code some sort of visual input and, I'd infer, to perform clustering, which permits it to assign labels (i.e. let's say, 'tree', 'human', etc.) to objects it has encountered. It can use this schema which it has constructed to assign objects it hasn't seen before to a cluster - that is, it labels novel inputs in accordance with its schema. Thus, the algorithm 'recognizes' classes of objects. I'd imagine if you granularize the detail level of detail

          • Your logic is flawed.

            By splitting object-recognition into two cases...
            A: Atomic shapes
            B: Collections of shapes ... you have not proven that algorithms cannot perform object-recognition. You still need to show that one of the cases cannot be performed by an algorithm. As case A is trivial, and case B is what this algorithm does your argument falls apart. Collections of shapes can be recognised by probability of occurrence. There is no need for interactivity, simply enough video

            • If you used video, rather than images (or frames from images taken in isolation), and the video showed how things are used, then you could get somewhere. For example each grape in a bowl of grapes is an "object" for eating purposes whereas each bump on a raspberry is not, despite how visually similar those are.
        • I don't see it that way because in the article and the BYU article the examples clearly lable a Tree a Tree, an Airplane an Airplane, and a Human a Human. Ether you're right and someone went though and relabeled the object ID labels with human readable versions, or you've given it more credit then then they are trying to take.

        The features part is really the tricky part. You could supply a set of pictures of aircraft and the algorithm would need to determine what is common to all those examples.
        With regards to training, It is possible to perform this learning task without direct supervised (tagged data) training.
        Imagine the following:
        Take a trillions of images from the web, and use unsupervised, clustering methods to group images into groups of equivalence, given that you have great features that allow you to do that.

        But that is exactly what people do. Other than a few hard-wired patterns (e.g. faces), we "learn" to recognize objects by being exposed to multiple examples of those objects and told the label to apply to them.

        Though the argument could be made that people don't learn on their own either...

      At least there's one professor at BYU that believes in evolution!

      I understand why it might be tempting to put BYU in a basket along with the rest of the evangelical christian universities. However, on the issue of evolution it could not be more different. I graduated from there with a degree in microbiology and my college at least evolution was the coin of the realm, just like it is in any serious biology department. I did not have a single professor that did not see evolution as you might expect a biologist to see it; as the only serious explanation of the data at hand, the only theory that works with what we know and provides valid predictions of future results. Not once did I hear even the smallest bit of credibility being given to creationism or its various variants (intelligent design, etc).

      And yes, my professors were all Mormons. You might ask yourself how they square this. It turns out that while there are certainly Mormons that take a very literal reading of the bible on this issue, that is not the official church position, and there are many members that don't see it that way at all. Basically I had several professors that explained it as religion was about how to live life, science was about how life works, and we really have no idea how the two come together. The bible, while providing a lot of information to believers on a moral life, provides no real information on how the world works in any of the scientific fields.

      Interestingly, many believe this is on purpose, that God has no interest in proving his existence; it's a matter of faith for a reason. Because of this He stays out of offering scientific explanations. I realize that sounds distinctly like a cope-out, but frankly it leads to a fairly rational place where you can function as a scientist an still be a Mormon. And by function I don't mean some half-way hands over eyes sort of a way, but in a real, go where the evidence takes you sort of a way.

      Take it for what it's worth, but that was my experience

      • I graduated from the Y too - and while most of my professors were not irrational about science, much of the student body was. I had a professor in a 100 level geology class who would start off most of his lectures by saying, "Now I know for some of you, your testimonies may tell you the earth is only such and such many years old. I'm not here to rock your testimonies or shake your faith, but simply to present scientific evidence as we understand it today."

        I laughed every time he had to make a disclaimer
        • Yea, I expect if you signed up for biology you tended to get over that pretty quick, or generally dislike your life. It's easier to have an irrational viewpoint about science as an English major where you don't have to face it to function each day.
        • "testimonies"? ...is that some specialized mormon terminology like being 'sealed' rather than married? i've read endless screeds about how one can make religion and science happily co-exist. but in the final analysis, it can't happen; at least not with standard faith-based religions. science essentially demands that nothing can be taken on faith; and religion essentially demands that anything important (the root of one's philosophical tree, if you will) must be taken on faith. if you're a faithful you
          • Indeed. "Testimonies" are very much along the lines of "I testify that I hold X/Y/Z ideas on faith." Every month (usually the first Sunday of each month) there is a special meeting fast and testimony meeting where members of the congregation get up and "bear their testimony." As a kid growing up with a dad teaching at BYU, these Sundays were the worst. They often dragged on longer than normal not just because church service ran longer, but the fasting portion of "fast and testimony" meant we were hungry a

          • I suppose this depends on a number of things, and perhaps in the end you may be right. But at the moment there really isn't a clear conflict; the conflict is more manufactured than real, especially if you see religion as a road to life happiness and not an explanation of all things. I admit that there is a certain about of dealing with ambiguity that is required. Frankly, I tend to be much more of an agnostic or a deist than your average Christian. I tend to believe that my life is mine to live, there i
