Computer model of spread of dementia can predict future disease patterns years before they occur in a patient

March 22, 2012


Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain.

They say their mathematical model can be used to predict where and approximately when an individual patient’s brain will suffer from the spread, neuron to neuron, of “prion-like” toxic proteins — a process they say underlies all forms of dementia.… read more

Computer model knows what you’re thinking

May 30, 2008

Carnegie Mellon University researchers have built a computer model that can predict which concrete noun (things that one can see, hear, feel, taste or smell) one is thinking about based on brain scans.

The model was trained to look at how words relate to sensory and movement information (“hammer” with movement areas), and how nouns are associated with 25 basic verbs (“celery” but not “airplane” with “eat”).

Computer model forecasts crime sprees

August 19, 2003

A more powerful tool for forecasting crime is emerging from a huge electronic database of six million crimes.

A team from Carnegie Mellon University analyzed the data in two ways: A statistical analysis that spots broad trends allowed researchers to quantify the rules of thumb that police officers often learn from experience; and a list leading indicators — minor offences such as vandalism and trespassing that crime analysts believe… read more

Computer Model Behaves Like Humans On Visual Categorization Task

April 3, 2007

In a new MIT study, a computer model designed to mimic the way the brain itself processes visual information performs as well as humans do on rapid categorization tasks.

The model even tends to make similar errors as humans, possibly because it so closely follows the organization of the brain’s visual system.

“We created a model that takes into account a host of quantitative anatomical and physiological data… read more

Computer memory that can store about one terabyte of data on a device the size of a postage stamp

Data density more than 50 times greater than flash memory; now a step closer to to mass production
July 14, 2014

High-density, next-generation computer memory that can store about one terabyte of data on a device the size of a postage stamp — more than 50 times the data density of current flash memory technology — is now a step closer to mass production.

That’s because Rice University’s breakthrough silicon oxide technology will allow manufacturers to fabricate “resistive random-access memory” (RRAM) devices at room temperature with conventional production… read more

Computer learns sign language by watching TV

July 9, 2009

Software developed in the UK has worked out the basics of sign language by absorbing TV shows that are both subtitled and signed.

Computer learning to read lips to detect emotions

Bright red female lips

Open the pod bay doorsHAL.

Scientists in Malaysia are teaching a computer to interpret human emotions based on lip patterns.

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 efficiently, says Karthigayan Muthukaruppan of Manipal International University.

The system uses a genetic algorithm that gets better and better… read more

Computer History Museum Minsky Event Cancelled

October 16, 2006

The Computer History Museum announced that due to a sudden family health matter, “An Evening with Marvin Minsky in Conversation with Nils J. Nilsson” has been cancelled.

Computer generates verifiable mathematics proof

April 20, 2005

Mathematicians have employed logic-checking software to help develop a proof of the Four Color Theorem. The method could be used to develop a similar system for checking the logic used in computer programs, which could pre-empt some unforeseen bugs that cause programs to crash.

The Four Color Theorem states that any four colors are the minimum needed to fill in a flat map without any two regions of the… read more

Computer games stunt teen brains

August 20, 2001

Computer games are creating a dumbed-down generation of children far more disposed to violence than their parents, according to a controversial new study by Professor Ryuta Kawashima and his team at Tohoku University in Japan.The level of brain activity was measured in hundreds of teenagers playing a Nintendo game and compared to the brain scans of other students doing a simple, repetitive arithmetical exercise. The computer game only stimulated activity… read more

Computer DJ uses biofeedback to pick tracks

November 16, 2001

A computerised DJ that uses feedback from the dancers to generate new music
has been developed by artificial intelligence experts at Hewlett-Packard.Each clubber has a device like a wristwatch that monitors their location,
heart and perspiration rate, and movement and feeds info back to the “HPDJ”
via a wireless link.

To create a song, the HPDJ chooses tracks from a large library and then modifies and overlays them, based… read more

Computer decodes dog communication

January 18, 2008

Computer software can distinguish individual dogs by their barks, and also suggests that certain barks act as a “universal language”, carrying information about the dog’s mind-set that is readily understood by their fellow pooches.

Computer crack funnier than many human jokes

December 20, 2001

An experiment to uncover the world’s funniest jokes has found that some computer-generated gags can be more amusing than those thought up by humans.

The Laugh Lab survey is being conducted through a web site, on which members of the public are invited to submit favourite jokes and rate other submissions. They are also asked to contribute information about themselves.

Five computer-generated gags were contributed by researchers at… read more

Computer components shrinking faster than predicted

February 23, 2009

Two U.S. groups have announced transistors almost 1000 times smaller than those in use today (features just 2 nanometers in size), and a version of flash memory that could store all the books in the US Library of Congress in a square 4 inches across at 10 terabits per square inch (current technology: .5 terabit), using nanoscale magnets.
