Computers Gone Wild

March 19, 2007

Symantec’s biannual “Internet Security Threat Report,” released Monday, reports that China has the highest number of botnet-infected computers, 26 percent of the world’s total. The U.S. came in second, with 14 percnet of the worldwide total.

Computers Get The Meaning

June 29, 2005

A new software language will let computers interpret the nuanced meaning behind a command in order to appropriately execute actions in manufacturing environments. Developed by federal government researchers at the National Institute of Standards and Technology and colleagues in France, Germany, Japan, and the United Kingdom, the process-specification-language software should make computers reason much more precisely than they do now.

Computers Get In Touch with Your Emotions

February 24, 2011

User monitoring system to optimize performance (Design Interactive)

With the emergence of new tools that can measure a person’s mental and physiological states, computer interfaces are starting to attention to how users feel to help computers cater to their needs, say experts.

Design Interactive is prototyping Next Generation Interactive Systems, or NexIS, a system that will place biological sensors on soldiers. If a sensor detects that a soldier’s pulse is weakening, or determines another problem with her… read more

Computers Get Help from the Human Brain

November 30, 2010

Columbia University researchers are using a BCI to help search rapidly through images.  (Paul Sajda, Columbia University)

Columbia University researchers are using brain-computer interfaces (BCI) to help computers perform tasks they can’t manage on their own.

Electrical signals within the brain fire before a person even realizes he’s recognized an image as odd or unusual. So in experiments,  the researchers used a BCI to sort through satellite images for surface-to-air missiles faster than any machine or human analyst could manage alone.

Computers gain power, but it’s not what you think

March 21, 2005

Performing complex tasks at lightning speed is the machine’s greatest strength; thinking and intelligence are still in our heads.

After decades of trying to create machines that can think, researchers now just want to take advantage of computers’ speed and make them less stupid.

Intellext’s Watson, which uses pattern recognition to find relevant documents, is one example of software that takes advantage of more powerful computers. Another is… read more

Computers found more accurate than doctors in breast-cancer diagnosis

November 10, 2011

A Stanford School of Medicine machine-learning-based method for automatically analyzing images of cancerous tissues and predicting patient survival was found more accurate than doctors in breast-cancer diagnosis, but doctors don’t trust this method, say MIT researchers (credit: Science/AAAS)

Computer analyses of breast cancer microscopic images were found more accurate than those conducted by humans, computer scientists at the Stanford School of Engineering and pathologists at the Stanford School of Medicine report.

The researchers’ Computational Pathologist (C-Path) is a machine-learning-based method for automatically analyzing images of cancerous tissues and predicting patient survival.

Since 1928, the way breast cancer characteristics are evaluated… read more

Computers estimate emotions

January 9, 2006

Researchers at the Fraunhofer Institute for Computer Graphics Research in Germany have developed a glove that senses a computer operator’s heartbeat and breathing rate, blood pressure, skin temperature and electrical resistance and connects to a device that infers emotions.

They are also working on techniques that will enable computers to interpret facial expressions and extract emotional elements from voice signals.

Scientists hope to develop the first treatment for smallpox by harnessing the “downtime” of two million PCs around the world.

Computers ‘could store entire life by 2026′

December 15, 2006

A device the size of a sugar cube will be able to record and store high resolution video footage of every second of a human life within two decades, according to speakers at the Memories for Life conference at the British Library.

Computers Can’t Answer Everything

November 19, 2009

The real power of natural language processing can only be unlocked by acknowledging its limitations and filling in the gaps with human intelligence, says Damon Horowitz, chief technology officer and cofounder of Aardvark.

“We wanted to let another human being answer and have the machine do the heavy lifting of indexing everybody–the tens of thousands of people who are in your extended network and all of the things that… read more

Computers Can Argue, Researcher Claims

August 30, 2004

Agent-based negotiation is a significant addition to our understanding of how to automate the sorts of complex behaviors that — until now — have been exhibited only by people.

Computers being taught 3D vision

June 14, 2006

Carnegie Mellon University scientists say new machine learning techniques are allowing them to teach computers to perceive three dimensions in 2-D images.

The discovery may ultimately find application in vision systems used to guide robotic vehicles, monitor security cameras and archive photos.

Computers as Authors? Literary Luddites Unite!

November 22, 2004

A computer program known as Brutus.1 is generating brief outbursts of fiction that are probably superior to what many humans could turn out.

Computerized moths diversify to survive

February 11, 2002

Real birds pecking virtual moths have shown how camouflage probably evolves. The computerized prey adapted to blend into their background, and developed a wide range of different markings.
University of Nebraska biologists made virtual moths. A set of computer instructions representing an electronic genome determined their wing patterns. The researchers trained captive blue jays to hunt the moths. Pecking at an on-screen moth earned a jay a food pellet. After… read more

Computerized Combat Glove

(Brittany Sauser)

RallyPoint, a startup based in Cambridge, MA, has developed a sensor-embedded glove that allows the soldier to easily view and navigate digital maps, activate radio communications, and send commands without having to take his or her hand off their weapon.

It includes four push-button sensors, a mouse funtion, three accelerometers, and an USB connection.
