New Approach to Distributing Computations Could Make Multicore Chips Much Faster

New Approach to Distributing Computations Could Make Multicore Chips Much Faster

Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel.   But the ways in which a chip carves up computations can make a big difference to performance. In a 2013 paper, Daniel Sanchez, the TIBCO Founders [...]

Building Trustworthy Big Data Algorithms

New algorithm can separate unstructured text into topics with high accuracy and reproducibility Much of our reams of data sit in large databases of unstructured text. Finding insights among emails, text documents, and websites is extremely difficult unless we can search, characterize, and classify their text data in a meaningful way. One of the leading [...]

Extracting Audio from Visual Information: Algorithm Recovers Speech from Vibrations of a Potato-Chip Bag Filmed through Soundproof Glass

Extracting Audio from Visual Information: Algorithm Recovers Speech from Vibrations of a Potato-Chip Bag Filmed through Soundproof Glass

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.   In other [...]

Computer Security: ‘Melbourne Shuffle’ Secures Data in the Cloud

Computer Security: ‘Melbourne Shuffle’ Secures Data in the Cloud

  To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle. That may sound like a dance move (and it is), but it’s also a computer algorithm developed by researchers at Brown University. The computing version of the Melbourne Shuffle aims to hide patterns that may emerge as [...]

A Simple Solution for Big Data: New Algorithm Simplifies the Categorization of Data

A Simple Solution for Big Data: New Algorithm Simplifies the Categorization of Data

A SISSA algorithm published in Science simplifies the categorization of data Experts use the expression big data to indicate huge amounts of information, such as those (photos, videos, texts, but also other more technical types of data) shared at any time by billions of people on computers, smartphones and other electronic devices. The present-day scenario [...]

Short Algorithm, Long-Range Consequences

Short Algorithm, Long-Range Consequences

In the last decade, theoretical computer science has seen remarkable progress on the problem of solving graph Laplacians — the esoteric name for a calculation with hordes of familiar applications in scheduling, image processing, online product recommendation, network analysis, and scientific computing, to name just a few. Only in 2004 did researchers first propose an [...]
