Tag Images With Your Mind 64

blee37 writes "Researchers at Microsoft have invented a system for tagging images by reading brain scans from an electroencephalograph (EEG). Tagging images is an important task because many images on the web are unlabeled and have no semantic information. This new method allows an appropriate tag to be generated by an AI algorithm interpreting the EEG scan of a person's brain while they view an image. The person need only view the image for as little as 500 ms. Other current methods for generating tags include flat out paying people to do it manually, putting the task on Amazon Mechanical Turk, or using Google Image Labeler."

    Honestly this is nice, but seriously if my mind was tagging my images there would be something like the following list of tags
    idhitit, awesome,ohgod, thehelliswrongwithme, whydidisavethisagain, ohthatswhy, shit, wallpaper, and photoshop
    and that's just keeping it within PG-13.

    • Using an EEG scan of a person's brain while they view an image could yield very different results for an image of a naked woman depending on the viewer's sex or sexual persuasion. Also, for images of objects and images of people in general - each viewer would have a different set of associations for a given image. For example, imagine the EEG of a person with arachnophobia when presented with a picture of a spider, etc.

  • From the summary:

    This new method allows an appropriate tag to be generated by an AI algorithm interpreting the EEG scan of a person's brain while they view an image.

    That's true, as long as "appropriate" means it was either X or Y, as the system really only works on discriminating between things like "a face" and "not a face". It's an interesting piece of research, sure, but it sure as hell won't replace good old fashioned tagging using a keyboard.

    • We could make registering minimal brain activity a requirement to access the internet, that should cut net population by about 90%.

  • An EEG is not the same thing as a "brain scan". An EEG is an analog point to point system which is very good at "reading" the parts of the generalized electrical field that reaches the scalp from the brain. Using EEG output to control stuff is a fun sideline which is almost exactly as old as EEG technology itself.

    It doesn't work very well, and it very probably never will. The variance in electrical activity in the brain between two people receiving the same sensory input is, in an average way, too great

      Actually, the variance isn't the problem. That comes out statistically in the wash - you can see that with a large enough N, patterns emerge across the different stimuli types, which allows them to do the tagging. The real problem is interpreting the complex interactions between the different regions of the brain. However, that doesn't really matter for an experiment like this, as the patterns don't actually need to be interpreted, just recognized by the algorithm. It's a similar concept to the way the MMP

      You shouldn't directly use the "thought pattern" of a person to tag the data.

      As you said, the thought patterns are likely to be different from person to person.

      What you do though is, for each tagging participant, you get the person's thought patterns for a whole bunch of tags.

    This is typical of MS -thinking that something like this would be easy for the average user. FTA: "However, the mind reading approach has the advantage that it does not require any work at all from the user."

    So, in order to use this sytem, we should all strap on EEG caps while we're surfing the web. Sounds real practical to me - I used to work in an EEG lab, and I can tell you that those caps are pretty uncomfortable to wear. After they put them on, you stick these little needles into the leads and squirt conductive goop on your scalp. It takes a few cycles to rinse that stuff out too.

    Way to go MS for making productivity so much easier.

      Smitty, we've come a long way from those caps. There are now "caps" that are essentially nets of elastic cord with plastic cups containing pieces of sponge in them, the electrodes embedded in the sponge. Dip it in mild salt water for conduction, shake it out so there's no drips running together bridging the electrode sites, and pull it on. I could get good signal on 128 channels in less than 10 minutes from the time they walked in to data collection start.

      There is also a European company selling a similar get up, but the preamps are built into the cups on the net, making impedance matching irrelevant and signal balancing automatic on the fly. These are so stable that they can be used ambulatory.

      And nobody ever has to get goop or glue stuck on/into them any more.

    unlabeled and have no computer-readable semantic information.

    There, fixed that for you.

    Seriously, the old saying "an image is worth 1,000 words" implies that images frequently have semantic information, at least in the sense that anything on paper can have semantic information. It's just that computers can't parse it, catalog it, search on it, etc. Not well, anyways, not yet. They are getting there though.

  • Just one minor nitnoid: the title of this article should be "Tagging Images With Your Brain", not Mind. Electrical impulses are used - using the word mind implies that some conscious effort is involved. This is strictly identifying patterns using machine algorithms independent of the user's thought process.

    Useful, but real-world tagging is much more specific than "person", "animal", or "inanimate". The number of classes required in the classification task is thus far greater and one would expect the accuracy to be proportionally lower. OTOH, it could be a great preprocessing step for further manual analysis, or a step in a hierarchical clustering algorithm. Or maybe 3 classes suffice for certain specific situations.

      If you were in a sensory deprivation tank with the only perceptual cue the target image, you'd still have hundreds to thousands of competing cognitions boiling away, fighting for processing space on their way to awareness, few of them making it but all taking up some resources and generating some signal. But these, as well as any ongoing stimulus like music, are not locked in time with the stimulus presentation and so are random as compared to the stimuli.

On the other hand, if the determined spammers out there figure out how to get a machine to do it, then they've done our work and we now have a machine that can tag photos.
