The active learning algorithm is faster and more accurate in guessing the age of an individual than conventional algorithms.

Scientists have created a new algorithm to detect virtual communities, designed to match the needs of real-life social, biological or information networks detection better than with current attempts.

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…

The prevalence of computer networks for sharing resources places increasingly high requirements on the reliability of data centers. The simplest way to diagnose abnormalities in these systems is to monitor the output of each component but this is not always effective.

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…

An expert comments on the Zappos web site breach by hackers. He said that information about a customer can be used to 'de-anonymize' other databases on other Web sites, further invading customer privacy.

Norwegian researchers have borrowed a page from game developers to devise simulation technology that can save lives in many parts of the world by helping to reduce the damage from catastrophic floods.

Computer scientists have developed a visualization tool known as DNSViz to help network administrators within the federal government and global IT community better understand Domain Name System Security (DNSSEC) and to help them troubleshoot problems.

Smartphones could help save hundreds of thousands of lives in the aftermath of a disaster or humanitarian crisis, new research has found.

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…

A new draft computer security publication provides guidance for vendors and security professionals as they work to protect personal computers as they start up.

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.

A simple online calculator could offer family GPs a powerful new tool in tackling two of the most deadly forms of cancer, say researchers.

We are at the dawn of the age of IPv6, the Internet protocol that will succeed version 4, experts say. With 340 undecillion available addresses, IPv6 ensures that the Internet can continue growing and offers advantages in terms of stability, flexibility, and simplicity in network administration.

Physicists have significantly improved the calculation method for scattering experiments in particle physics. This kind of calculation is used to predict the outcome of accelerator experiments in which high-energy particles collide with one another. However, the calculations become increasingly difficult the greater the number of orders the physicists wish to…
