Scientists Build Mind-Reading Computer

An anonymous reader writes to tell us that researchers from Carnegie Mellon University have developed what they are calling a "mind reading computer." Using a panel of nine volunteers, the team built a "profile" of 58 test words based on brain scans taken while the volunteers were directed to think about the meaning of each test word. "'If I show you the brain images for two words, the main thing you notice is that they look pretty much alike. If you look at them for a while you might see subtle differences,' explains Tom Mitchell of the Machine Learning Department, which lead the study. 'We believe we have identified a number of the basic building blocks that the brain uses to represent meaning. These building blocks could be used to predict patterns for any concrete noun,' added Mitchell."

      I haven't read TFA, but I was just reading the actual scientific article before I came here. Your objection doesn't quite apply for a similar reason to what you mention: the software was separately trained for each of the nine subjects. For each subject you give them a set of different words (it was 60 words, five from each of 12 different categories of concrete nouns) and record an fMRI of each one.

      Now what you do is drop two of those out, train the software on 58 words, and see how well it can guess which words the other 2 were. They show that they are pretty good at predicting the two untrained words.

      The interesting bit is how they do this: they basically form a mathematical space with 25 dimensions corresponding to simple sensory-motor features (e.g. eating, nearness, touching, pushing, running, etc.). It is then a matter of using linear regression to break down the brain's responses to each of the trained words into this 25 dimensional space. Then you can turn the system around the other way and use semantic information about the words (calculated based on covariance of work occurrence form a large corpus of text) to predict what the brain activity should be for a given word, then pick the word whose predicted pattern is closest to the experimentally determined pattern.

      It is pretty neat work.

      Most interesting is that they tried a number of random 25-element bases instead of the hand selected one and showed they offered much lower predictive ability. That supports theories that cortical representation of the words does in fact break down into sensory-motor categories of the type they hand selected.

    Yet again we see a jounalist dumbing down scientific research into tabloid fodder.


    What the CMU scientists have done is some preliminary brain imaging using MRI.

    Here is a better CMU link with more details and pictures. The scientists hope that this research to could have applications in the study of autism, disorders of thought such as paranoid schizophrenia, and semantic dementias such as Pick's disease. Not once did they ominously dub their research as "mind reading" as claimed by the submitter.

The resulting brain scan image superimposes the oxygen demand levels in red-yellow-green-blue scale over a monochrome image of that slice of the brain. Effectively, they see which areas of the brain are in use from second to second.

      Errm... Unless you regard electrons as 'non-physical objects' then your computer *does* physically change constantly as more/less electrons flow to different parts. This is illustrated by the processor core temperature increasing/decreasing, which I think most people would also regard as a 'physical change'.

    The implications of building blocks would suggest that the french word for "Desk" (bureau) would elicit the same response as the english word for "Desk", instead of some governmental unit.

    That would be useful, (once we get cheap portable MRI hats).

    However I doubt these building blocks are anywhere near that generic due to the excess emotional baggage that people associate with words. I suppose it might be able to detect the presence of such baggage even if it could not decipher it.

    Phrenology was 19th century "science" of discerning personality types by look at fine detail of skull shape. This shares some aspects with 21st century brain scans:
    (1) They are both based on head geometry. Phrenology just looked at the surface, while MRI looks at volumes.
    (2) They are both derived from empirical measurements, rather than first-principles of why geometry is the way it is. This is not bad if it really works. Although more people would believe it if the underlying mechanisms for the geometric patterns were known, and improving the predictablity of new patterns.
    (3) There seems to be some degree of interpretation of data. This degenerated into prejudice against certain kinds of humans for phrenology, eventually defeating that method. Supposedly in the 21st century there is more objective statistical discrimination of results.
