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...

Artificial neural network model proves accurate in classification study Irrigating 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 choices. "The...

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 more Facebook 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 networks...

Altering the DNA of a zebra finch could reveal the process of vocal learning in vertebrate brains, scientists at New York's Rockefeller University say. The zebra finch is one of several of its species that learn to speak by imitating other zebra finches, said Fernando Nottebohm, who heads the Laboratory of Animal Behavior at Rockefeller University. By manipulating the genes of zebra finches, Nottebohm and his team hope to learn more about the neural circuitry that allows songbirds to learn...

Computer scientists in Taiwan say they've developed a neural network computer program that can classify computerized music based on its beat and tempo. Mao-Yuan Kao and Chang-Biau Yang of National Sun Yat-sen University in Kaohsiung and Shyue-Horng Shiau of Chang Jung Christian University in Tainan said their system could assist music archivists with an automated approach that assigns a genre to each tune. They said their artificial neural network is a type of computer model that mimics the...

Computer scientists in Taiwan have devised a neural network program that can successfully classify a computerized music file based on its beat and tempo. The system could be a boon for music archivists with large numbers of untagged recordings and for users searching through mislabeled mp3 libraries. Details of tests on ballroom dancing music are reported this month in the International Journal of Intelligent Information and Database Systems.Mao-Yuan Kao and Chang-Biau Yang of National Sun...

Researchers from the Hebrew University of Jerusalem have succeeded for the first time in devising a model that describes and identifies a basic cellular mechanism that enables networks of neurons to efficiently decode speech in changing conditions.The research may lead to the upgrading of computer algorithms for faster and more precise speech recognition as well as to the development of innovative treatments for auditory problems among adults and young people.Our brain has the capability to...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
