An Artificial Intelligence (AI) library covering use of Artificial Neural Networks (ANN) in applications. This library can be used to build market analysis, sales forecasting, industrial process control, customer research, data validation, risk management, target marketing and Optical Character Recognition (OCR) applications (a simple OCR demo included) and may have millions other uses. The library implements basic set of neural networks - Adaline, Backpropagation (BP), Bi-directional Associative Memory (BAM) and Self-Organizing networks (SON). The library is useful for people who want to understand, implement or use neural networks. Its object-oriented approach makes it easy to use and very extensible.
