Researchers advance biometric security

  • PDF
TechAndComputer (June 21, 2012) — Researchers in the Biometric Technologies Laboratory at the university have developed a way for security systems to combine different biometric measurements -- such as eye colour, face shape or fingerprints -- and create a learning system that simulates the brain in making decisions about information from different sources.

Professor Marina Gavrilova, the founding head of the lab -- among the first in the research community to introduce and study neural network based models for information fusion -- says they have developed a biometric security system that simulates learning patterns and cognitive processes of the brain.

"Our goal is to improve accuracy and as a result improve the...

All things big and small: The brain's discerning taste for size

  • PDF
TechAndComputer (June 20, 2012) — The human brain can recognize thousands of different objects, but neuroscientists have long grappled with how the brain organizes object representation; in other words, how the brain perceives and identifies different objects. Now researchers at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) and the MIT Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size, with a...

Robots get a feel for the world: Touch more sensitve than a human's

  • PDF
TechAndComputer (June 18, 2012) — What does a robot feel when it touches something? Little or nothing until now. But with the right sensors, actuators and software, robots can be given the sense of feel -- or at least the ability to identify different materials by touch.

Researchers at the University of Southern California's Viterbi School of Engineering published a study June 18 in Frontiers in Neurorobotics showing that a specially designed robot can outperform humans in...

New discoveries with language learning robots

  • PDF
TechAndComputer (June 14, 2012) — Robots can develop basic language skills through interaction with a human, according to new results from researchers at the University of Hertfordshire and published in PLoS ONE.

Dr Caroline Lyon, Professor Chrystopher Nehaniv and Dr Joe Saunders have carried out experiments as part of the iTalk project with the childlike iCub humanoid robot to show how language learning emerges. Initially the robot can only babble and perceives speech as a...

Robotic assistants may adapt to humans in the factory

  • PDF
TechAndComputer (June 13, 2012) — In today's manufacturing plants, the division of labor between humans and robots is quite clear: Large, automated robots are typically cordoned off in metal cages, manipulating heavy machinery and performing repetitive tasks, while humans work in less hazardous areas on jobs requiring finer detail.

But according to Julie Shah, the Boeing Career Development Assistant Professor of Aeronautics and Astronautics at MIT, the factory floor of the...
