Researchers at IBM say they have developed a new algorithm that can analyze terabytes’ worth of raw data in a matter of minutes. The algorithm could be used to more quickly predict weather, electricity usage and water pollution levels, for instance. It could analyze data gathered from sources such as sensors or smart meters, as well as break down data from global financial markets and assess individual and collective exposure to risk.
The mathematical algorithm, developed by IBM’s laboratories in Zurich, can sort, correlate and analyze millions of random data sets, a task that could otherwise take days for supercomputers to process, said Costas Bekas, a researcher at IBM.
The traditional approach to data analysis is to take multiple data sets and look at them individually, said Eleni Pratsini, manager of mathematical and computational sciences at the IBM research labs. However, the algorithm compares data sets against each other, which could help enterprises point toward larger trends in particular areas, such as risk reduction in financial portfolios.
The new algorithm combines models of data calibration and statistical analysis that can assess measurement models and hidden relationships between data sets.
The algorithm can also reduce the cost burden on companies by analyzing data in a more energy-efficient way, Bekas said. The lab used a Blue Gene/P Solution system at the Forschungszentrum Julich research center in Germany to validate 9TBs of data in less than 20 minutes. Analyzing the same amount of data without the algorithm would have taken a day with the supercomputer operating at peak speeds, which would have added up to higher electricity bills, Bekas said.
Now that the algorithm has been shown to work, it may soon be used in IBM software applications.

The 808 PureView device from Nokia, which comes fixed with a 41-megapixel camera, is surely the last big thing that we have seen from the Symbian platform. The camera of the device pitches it will ahead of others to the top-of-the-range devices and a comparison between the performance of 808 PureView images with those of HTC One S and iPhone 4S shows what a 41-mp camera is capable of.
Microsoft has been pursuing Motorola for quite some time in courts. The reason was that Microsoft alleged Motorola infringed one of its patents by including certain texting features in its smartphones. These features, according to Microsoft, are owned by the company and Motorola should have bought a license to use them. And it seems now that a German court agrees.
Google has been steadily working on its Project Glass and the prototype glasses from the project are being tested publicly by a number of Google personnel. While many have cast doubts as to whether or not these prototypes are fully functional and operate on their own, Google seems quite confident of the progress. The search giant has now unveiled the first video samples from the project.
Apple’s Siri has been lauded as one of the best voice-enabled personal assistants available. Although Siri is quite good, it is not perfect and does make mistakes. And now, Siri has a worthy contender in the form of S Voice, the voice assistant that Samsung unveiled to be a part of Samsung Galaxy S III. Galaxy S III will soon be in the hands of the consumers and S Voice will be pitted against Siri. Here’s a fairly accurate comparison of the two.
