  OVERVIEW OF NEURAL NETWORKS
Nonetheless, network behavior is important, especially in light of evidence for so-called "emergent properties", ie, properties of networks that are not obvious from an understanding of neuron physiology.
Although neural networks as they are implemented on computers were inspired by the function of biological neurons, many of the designs have become far removed from biological reality.
Computer neural network models are described in terms of their architecture (patterns of connection) and in terms of the way they are trained (rules for modifying weights).

 Neural Networks
Autoassociative networks are feedforward networks whose inputs and outputs are identical with network training aimed at approximating the consequent identity mapping between network input and output.
The network consists of an input layer followed by a non-linear hidden layer (the bottleneck layer), a second non-linear hidden layer and finally the output layer of the same dimension as the input.
The industrial application of neural network modelling in the general area of process engineering have demonstrated their significant potential in process modelling and control with applications in polymersisation, bioprocessing and the modelling of chemical engineering unit processes.

  Neural Networks Introduction
Neural networks have been shown to be particularly useful in solving problems where traditional artificial intelligence techniques involving symbolic methods have failed or proved inefficient.
A three-layer backpropagation neural network was developed to predict the frequency of serious ADR cases for 17 particular NOSAIDs, using four inputs, each representing a particular property of the drugs.
Such a neural network might be used to predict the ADR rate for new drugs, as well as to determine the properties that tend to make for "safe" drugs.

 Neural Networks
Neural networks have seen an explosion of interest over the last few years, and are being successfully applied across an extraordinary range of problem domains, in areas as diverse as finance, medicine, engineering, geology and physics.
This is the type of network discussed briefly in previous sections: the units each perform a biased weighted sum of their inputs and pass this activation level through a transfer function to produce their output, and the units are arranged in a layered feedforward topology.
Neural network error surfaces are much more complex, and are characterized by a number of unhelpful features, such as local minima (which are lower than the surrounding terrain, but above the global minimum), flat-spots and plateaus, saddle-points, and long narrow ravines.

 Neural Networks
Neural networks, with their remarkable ability to derive meaning from complicated or imprecise data, can be used to extract patterns and detect trends that are too complex to be noticed by either humans or other computer techniques.
The commonest type of artificial neural network consists of three groups, or layers, of units: a layer of "input" units is connected to a layer of "hidden" units, which is connected to a layer of "output" units.

 Neural Networks & Connectionist Systems
Neural models of intelligence emphasize the brain's ability to adapt to the world in which it is situated by modifying the relationships between individual neurons.
Neural networks are usually characterized in terms of the number and types of connections between individual processing elements, called neurons, and the learning rules used when data is presented to the network.
Neural networks, unlike fuzzy logic, seek to reproduce the versatility of the human brain in recognizing the end-to-end, input-to-output behavior of a system without understanding all the processes taking place within it.

 generation5 - An Introduction to Neural Networks
This area of neural networking is the "fuzziest" in terms of a definite set of rules to abide by.
Neural networks are designed to work with patterns - they can be classified as pattern classifiers or pattern associators.
Other problems with neural networks are the lack of defining rules to help construct a network given a problem - there are many factors to take into consideration: the learning algorithm, architecture, number of neurons per layer, number of layers, data representation and much more.

Neural networks are simplified models of the brain composed of large numbers of units (the analogs of neurons) together with weights that measure the strength of connections between the units.
Neural networks are also particularly well adapted for problems that require the resolution of many conflicting constraints in parallel.
This suggests that neural network models serve as counterexamples to the idea that the language of thought is a prerequisite for human cognition.
