A wearable FES-robot hybrid training system has been designed for multi-joint upper limb rehabilitation. With successful combination of the two technologies' advantages, recovery achieved by the hybrid system was more prominent than using either technology alone in pilot clinical trials.

Computer intelligence system developed for acute stroke detection

ScienceDaily's AI News - Thu, 14/05/2015 - 09:57
A novel computer-aided detection system has been developed for acute stroke using computer intelligence technology. The detection accuracy is 90 percent, which is as high as that conducted by specialists, but at a much reduced time from 10-15 minutes to three minutes. The new system serves as a second opinion for frontline medical doctors, enabling timely and appropriate treatment for stroke patients.

Not good at sports strategies? Game intelligence can be learned

ScienceDaily's AI News - Thu, 14/05/2015 - 08:57
New theories on game intelligence could change the world of team sports forever. Game intelligence is not necessarily something you are born with but something you can learn, according to new research.

Novel computer intelligence system for acute stroke detection

ScienceDaily's AI News - Tue, 12/05/2015 - 11:23
Medical researchers have developed a novel computer-aided detection system for acute stroke using computer intelligence technology. The detection accuracy is 90%, which is as high as that conducted by specialists, but at a much reduced time from 10-15 minutes to 3 minutes.

Ants' movements hide mathematical patterns

ScienceDaily's AI News - Tue, 12/05/2015 - 10:35
When ants go exploring in search of food they end up choosing collective routes that fit statistical distributions of probability. This has been demonstrated by a team of mathematicians after analyzing the trails of a species of Argentine ant. Studies like this could be applied to coordinate the movement of micro-robots in cleaning contaminated areas for example.

Controlling swarms of cooperative robots with light and a single finger

ScienceDaily's AI News - Tue, 12/05/2015 - 07:54
Using a smart tablet and a red beam of light, researchers have created a system that allows people to control a fleet of robots with the swipe of a finger.

Important step in artificial intelligence: Stylized letters classified by their images

ScienceDaily's AI News - Mon, 11/05/2015 - 17:28
A circuit implementing the rudimentary artificial neural network successfully classified three letters by their images.

New device could greatly improve speech and image recognition

ScienceDaily's AI News - Mon, 11/05/2015 - 17:27
Researchers have successfully demonstrated pattern recognition using a magnonic holographic memory device, a development that could greatly improve speech and image recognition hardware.

Robot pets to rise in an overpopulated world

ScienceDaily's AI News - Mon, 11/05/2015 - 12:52
Robotic dogs are likely to replace the real thing in households worldwide in as little as a decade, as our infatuation with technology grows and more people migrate to high-density city living.

System designed to label visual scenes turns out to detect particular objects too

ScienceDaily's AI News - Fri, 08/05/2015 - 14:03
Object recognition -- determining what objects are where in a digital image -- is a central research topic in computer vision. Researchers have now demonstrated that, en route to learning how to recognize scenes, a new computer system also learned how to recognize objects.

Engineers hand 'cognitive' control to underwater robots

ScienceDaily's AI News - Fri, 08/05/2015 - 10:58
For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species. In general, such robots are effective at carrying out low-level tasks, specifically assigned to them by human engineers -- a tedious and time-consuming process for the engineers. Now a new programming approach gives robots more "cognitive" capabilities, enabling humans to specify high-level goals, while a robot performs high-level decision-making to figure out how to achieve these goals.

Researchers hack a teleoperated surgical robot to reveal security flaws

ScienceDaily's AI News - Thu, 07/05/2015 - 14:53
How safe is that robot doing your surgery? Researchers easily hacked a next generation teleoperated surgical robot to test how easily a malicious attack could hijack remotely-controlled operations in the future and to offer security solutions.

Soft robot: Shaping itself and moving with own internally generated power?

ScienceDaily's AI News - Tue, 05/05/2015 - 10:24
What if a new material would allow for development of a 'soft robot' that could reconfigure its own shape and move using its own internally generated power?

Combining computer vision, brain computer interface for faster mine detection

ScienceDaily's AI News - Mon, 04/05/2015 - 14:18
Computer scientists have combined sophisticated computer vision algorithms and a brain-computer interface to find mines in sonar images of the ocean floor.
