A Boost to Your Mobile Signal

A Boost to Your Mobile Signal

When using your mobile phone, it doesn’t take much to lose that precious signal — just turning a corner or riding on a train can be enough. EU-funded research is developing new technologies to eradicate those annoying ‘black holes’ in wireless coverage, while freeing up some mobile network capacity at the same time. We live […]

Smart Search Engines for News Videos

Smart Search Engines for News Videos

Searching for video recordings regularly pushes search engines to their limit. The truth of the matter is that purely automatic algorithms are not enough; user knowledge has to be harnessed, too. Now, researchers are making automated engines smarter. Anyone who has visited one of the big online video portals or TV broadcasters’ media libraries to […]

Smartphones Might Soon Develop Emotional Intelligence: Algorithm for Speech-Based Emotion Classification Developed

Smartphones Might Soon Develop Emotional Intelligence: Algorithm for Speech-Based Emotion Classification Developed

If you think having your phone identify the nearest bus stop is cool, wait until it identifies your mood. New research by a team of engineers at the University of Rochester may soon make that possible. At the IEEE Workshop on Spoken Language Technology on Dec. 5, the researchers will describe a new computer program […]

Leap Forward in Brain-Controlled Computer Cursors: New Algorithm Greatly Improves Speed and Accuracy

Leap Forward in Brain-Controlled Computer Cursors: New Algorithm Greatly Improves Speed and Accuracy

Stanford researchers have designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts. The algorithm’s speed, accuracy and natural movement approach those of a real arm, doubling performance of existing algorithms. These diagrams trace the accuracy of various trial scenarios of the ReFIT […]

Making Sudoku Puzzles Less Puzzling

Making Sudoku Puzzles Less Puzzling

For anyone who has ever struggled while attempting to solve a Sudoku puzzle, University of Notre Dame complex networks researcher Zoltan Toroczkai and Notre Dame postdoctoral researcher Maria Ercsey-Ravasz are coming to the rescue. They can not only explain why some Sudoku puzzles are harder than others, they have also developed a mathematical algorithm that […]

Training Computers to Understand the Human Brain

Training Computers to Understand the Human Brain

Tokyo Institute of Technology researchers use fMRI datasets to train a computer to predict the semantic category of an image originally viewed by five different people. The activation maps of the two contrasts (hot color: mammal > tool ; cool color: tool > mammal) computed from the 10 datasets of our participants. (Credit: Image courtesy […]

A Travelling Salesman Problem Special Case: 30-Year-Old Problem Solved

The science of computational complexity aims to solve the TSP — the Travelling Salesman Problem — when the time required to find an optimal solution is vital for practical solutions to modern-day problems such as air traffic control and delivery of fresh food. Warwick Business School’s Dr Vladimir Deineko and colleagues have now solved a […]

Computer Program Can Identify Rough Sketches

Computer Program Can Identify Rough Sketches

First they took over chess. Then Jeopardy. Soon, computers could make the ideal partner in a game of Draw Something (or its forebear, Pictionary). Ears and whiskers are a hint: Computers can recognize photos and careful drawings of rabbits, but quick sketches by non-artists … not so much. Researchers in Providence and Berlin say they […]

Computer, Read My Lips: Emotion Detector Developed Using a Genetic Algorithm

Computer, Read My Lips: Emotion Detector Developed Using a Genetic Algorithm

A computer is being taught to interpret human emotions based on lip pattern, according to research published in the International Journal of Artificial Intelligence and Soft Computing. The system could improve the way we interact with computers and perhaps allow disabled people to use computer-based communications devices, such as voice synthesizers, more effectively and more […]
