hi this a article about the neural network and their importance. A neural network is composed of a number of nodes, or units, connected by links. Each link has a numeric weight associated with it. Weights are the primary means of long-term storage in neural networks, and learning usually takes place by updating the weights. Some of the units are connected to the external environment, and can be designated as input or output units. The weights are modified so as to try to bring the network's...Read Full Story
Neural networks — collections of artificial neurons or nodes set up to behave like the neurons in the brain — can be trained to carry out a variety of tasks, often having something to do with pattern or sequence recognition. As such, they have shown great promise in image recognition systems. Now, research coming out of the University of Hong Kong has shown that neural networks can hear as well as see. A neural network there has learned the features of sound, classifying songs into specific...Read Full Story
The previous S&P-500 Neural Network forecast failed due to very positive news factors including strong second-quarter earnings reports. The following chart represents S&P-500 technical forecast for July 12 – 16, 2010. The calculation has been performed using Neural Network Stock Trend Predictor NNSTP-2 . The forecast is almost flat.Read Full Story

What is a Neural Network?
First of all, when we are talking about a neural network, we should more properly say “artificial neural network” (ANN), because that is what we mean most of the time. Biological neural networks are much more complicated than the mathematical models we use for ANNs. But it is customary to be lazy and drop the “A” or the “artificial”.

Researchers have been wondering for a long time how humans learn. After all, no one is born with an understanding of math or language, yet both of these develop throughout early life. In the case of math at least, many forms of life, including humans, have demonstrated an ability to understand when one set is larger than another, without counting the items. Now a virtual neural network has done the same.
This neural network was designed only...
(PhysOrg.com) -- A cognitive sciences research duo out of Università di Padova, in Italy, have succeeded in building an artificial intelligence network that has through repetition, learned to identify relative group sizes, without counting.

After taking the Stanford Machine Learning class offered over the Internet last year, [David Singleton] thought he could build something really cool. We have to admit that he nailed it with his neural network controlled car. There’s not much to the build; it’s just an Android phone, an Arduino and a toy car. The machine [...]
If you own a credit card, chances are you’ve heard about Falcon, the all-seeing technology that monitors your purchases and looks out for signs of fraud. Despite the name, it’s not actually a cybernetic bird or the world’s most financially-savvy car. In reality, it’s a complex neural network “held in secure servers at separate, top-secret locations”.
That’ ...

A community portal about Neural networks with blogs, videos, and photos. According to Wikipedia.org: A neural network is a computing paradigm that is loosely modeled after cortical structures of the brain. It consists of interconnected processing elements called neurons that work together to produce an output function. The output of a neural network relies on the cooperation of the individual neurons within the network to operate. Processing of information by neural networks is often done in parallel rather than in series. Since it relies on its member neurons collectively to perform its function, a unique property of a neural network is that it can still perform its overall function even if some of the neurons are not functioning. That is, they are very robust to error or failure.
