Facebook is a community
|
Researchers in Italy have used two high-speed computer algorithms to analyze the connections between a large sub-set of the more than half a billion users of the social networking site Facebook to reveal that the system has a very strong structure. The study shows that Facebook has a well-defined community structure that follows a statistical power law in which there are a huge number of people with few connections and a much smaller number with a large number of connections.

Faster-than-fast Fourier transform
|
Researchers have developed a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform. Under some circumstances, the improvement can be dramatic -- a tenfold increase in speed. The new algorithm could be particularly useful for image compression, enabling, say, smartphones to wirelessly transmit large video files without draining their batteries or consuming their monthly bandwidth allotments.

Crucial advances in 'brain reading' demonstrated
|
A new study demonstrates several crucial advances in "brain reading" or "brain decoding" using computerized machine learning methods. Researchers classified data taken from people being scanned while watching videos meant to induce nicotine cravings and detected whether people were watching and resisting cravings, indulging in them, or watching videos that were unrelated to smoking or cravings.

Computer vision research: Do you see what I see?
|
A question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply "looking" at an image. But teaching a computer to "know" what it's looking at is far harder. Scientists have now modeled human brain structure to develop better programming approaches for computer object identification.
