How the Met Office is solving the British weather with High Performance Computing

If you’re looking for big data, just look up. Weather analysis requires petascale-class pipelines, with seven-day forecasts needing approximately 2000 time-steps for prediction, and each time-step requiring trillions of computer operations. Weather forecasting and climate simulations can encompass quadrillions of operations for a single forecast run – which needs to be done several times a… Read More

New coreset technique makes big data manageable

A new technique for generating coresets within larger data sets has been discovered, which can help operators manage and analyze big data more efficiently. Shrinking an extremely large data set to a smaller subset that maintains necessary relationships is a known method of efficient analysis of large data sets. The newly discovered technique uses coresets… Read More

A new system architecture against big data insider threats

Much as law came later to the old west than the original settlers, security is coming late to big data.

U.S. Agriculture Department opens nutrition database

The U.S. Department of Agriculture has opened up its database of nutritional information to accept submissions from food manufacturers, creating a publicly-accessible nutrition index of grocery items. The Agriculture Research Service’s (ARS) Food Composition Databases has existed for almost a century, but only ever reached up to around 8,000 entries. Since opening up the campaign… Read More

UK gov: AI growth could reidentify individuals from big data

A new report from the UK’s Government Office For Science warns that the explosive growth in artificial intelligence, driven by Big Data, could mean that anonymised individuals in datasets might be extraordinarily easy to re-identify, due to the interlinking of vast, semi-supervised systems. In the report, entitled Research and analysis: Artificial intelligence: an overview for… Read More

Telco CEO: Consumers have ‘double standards’ over data privacy

Despite consumers continuing to criticise corporate attempts at monetising data, they are happily handing over data to major tech companies such as Facebook, according to the head of Telefonica Deutschland, Thorsten Dirks.
