Backpropagation - Wikipedia, the free encyclopedia
Backpropagation , or propagation of error , is a common method of teaching artificial neural networks how to perform a given task. It was first described by Paul Werbos in 1974, but it wasn't until...

With neural network technology, we can use parallel processing methods to solve some real-world problems where it is very difficult to define a conventional algorithm. ... This article focuses on a particular type of neural network model, known as a "feed-forward back-propagation network". This model is easy to understand,

Backpropagation neural network training model, explanations and algorithms ... Understanding Backpropagation ... Let's call this error eo for a particular output unit o. We have to bring eo to zero The simplest method to do this is the greedy method: we strive to change the connections in the neural network in such a way that,

algorithm backpropagation; During the Backpropagation stage of the neural network training, the output layer of neurons is adjusted, to make the output closer to what it need to be. Then the layer before is adjusted, based on the adjusted last layer and so on.

The utility of artificial neural network models lies in the fact that they can be used to infer a function from observations. This is particularly useful in applications where the complexity of the data or task makes the design of such a function ... We train our backpropagation neural network using the following examples:

Our goal is to introduce students to a powerful class of model, the Neural Network. In fact, this is a broad term which includes many diverse models and approaches. We will first motivate networks by analogy to ... We then introduce one kind of network in detail: the feedforward network trained by backpropagation of error.

Backpropagation neural networks employ one of the most popular neural network learning algorithms, the Backpropagation (BP) algorithm. It has been used successfully for wide variety of applications, such as speech or voice recognition, image pattern recognition, medical diagnosis, and automatic controls.
