approach‚ Neural networks are computer algorithms inspired by the way information is processed in the nervous system. An important difference between neural networks and other AI techniques is their ability to learn. The network ”learns” by adjusting the interconnection (called weights) between layers. When the network is adequately trained‚ it is able to generalize relevant output for a set of input data. A valuable property of neural networks is that of generalization‚ whereby a trained neural network

that are already in the data but were previously unseen. The most popular tool used when mining is artificial intelligence (AI). AI technologies try to work the way the human brain works‚ by making intelligent guesses‚ learning by example‚ and using deductive reasoning. Some of the more popular AI methods used in data mining include neural networks‚ clustering‚ and decision trees. Neural networks look at the rules of using data‚ which are based on the connection found or on a sample set of data

Demand Forecasting Demand forecasting is the activity of estimating the quantity of a product or service that consumers will purchase. Demand forecasting involves techniques including both informal methods‚ such as educated guesses‚ and quantitative methods‚ such as the use of historical sales data or current data from test markets. Demand forecasting may be used in making pricing decisions‚ in assessing future capacity requirements‚ or in making decisions on whether to enter a new market.

2.3.3 Feature Extraction Feature extraction deals with the extraction of the distinctive features out of face images so that those face images can be differentiated among each other. There are several algorithms available for extracting features out of a face image. The most common is the use of mathematical formulas that generate a mathematical representation of a face image that is termed as a template‚ these templates are “the refined‚ processed and stored representation of the distinguishing

The use of these techniques makes it very easy and cost effective to design reactors for specific needs and in cases where similar production procedures do not exist. This can reduce the time taken in the development of reactors.
