Mathematicians from Queen Mary, University of London will bring researchers one-step closer to understanding how the structure of the brain relates to its function in two recently published studies. Publishing in Physical Review Letters the researchers from the Complex Networks group at Queen Mary’s School of Mathematical Sciences describe how different areas in the brain can have an association despite a lack of direct interaction. The team, in collaboration with researchers in...
Paper offers a mathematical formulation of the brain's neural networks As computer scientists this year celebrate the 100th anniversary of the birth of the mathematical genius Alan Turing, who set out the basis for digital computing in the 1930s to anticipate the electronic age, they still quest after a machine as adaptable and intelligent as the human brain. Now, computer scientist Hava Siegelmann of the University of Massachusetts Amherst, an expert in neural networks, has taken...
Scientists from the University of Wisconsin have successfully had implanted neurons, created in laboratory conditions, connect with the brains of mice and both send and receive signals. In research published Monday in the journal Proceedings of the National Academy of Sciences (PNAS), lead author Jason P. Weick and associates Yan Liu and Su-Chun Zhang describe how they were able to take blank slate human embryonic stem cells (hESC), turn them into neurons, implant them into the brains of...
Molecular soup exhibits brainlike behaviorArtificial intelligence has been the inspiration for countless books and movies, as well as the aspiration of countless scientists and engineers. Researchers at the California Institute of Technology (Caltech) have now taken a major step toward creating artificial intelligence"”not in a robot or a silicon chip, but in a test tube. The researchers are the first to have made an artificial neural network out of DNA, creating a circuit of interacting...
In the wild, mammals survive because they can see and evade predators lurking in the shadowy bushes.That ability translates to the human world. Transportation Security Administration screeners can pick out dangerous objects in an image of our messy and stuffed suitcases. We get out of the house every morning because we find our car keys on that cluttered shelf next to the door.This ability to recognize target objects surrounded by distracters is one of the remarkable functions of our nervous...
Artificial neural network model proves accurate in classification studyIrrigating agricultural crops places huge demands on water resources around the globe. In Spain for instance, where agriculture is a major contributor to the nation's economy, 85% of country's total water demand comes from the agricultural sector. The excessive use of irrigation water has resulted in serious environmental concerns in Mediterranean countries, where rising demand has deteriorated groundwater resources,...
There are already systems that detect ships at sea, but a group of engineers from the UAH, led by the researcher Raúl Vicen, has introduced a new development, involving "the use of artificial intelligence techniques and improvements in the templates used to select input data".The team has come up with a new detection method "that outperforms the one that has generally been used until now, as well as offering the advantages of low computational costs, and which can also be...
A new University of Colorado at Boulder study sheds light on the brain mechanisms that allow us to make choices and ultimately could be helpful in improving treatments for the millions of people who suffer from the effects of anxiety disorders.In the study, CU-Boulder psychology Professor Yuko Munakata and her research colleagues found that "neural inhibition," a process that occurs when one nerve cell suppresses activity in another, is a critical aspect in our ability to make...
A statistical analysis of publicly available heart rate data using three classification tools - Random Forests, Logistic Model Tree and Neural Network - could lead to a rapid and precise way to diagnose heart problems, according to research in the International Journal of Electronic Healthcare."Heart rate and Heart Rate Variability (HRV) are important measures that reflect the state of the cardiovascular system. HRV analysis has gained prominence in the field of cardiology for detecting...
New method tackles social networks, biological systems, air transportation and moreFacebook figures out that you know Holly, although you haven't seen her in 10 years, because you have four mutual friends -- a good predictor of direct friendship. But sometimes Facebook gets it wrong. "Hey, I don't know Harry!"Roger Guimera and Marta Sales-Pardo, a husband-wife research team at Northwestern University, have developed a universal method that can accurately analyze a range of complex...
