Attention is focused in this book on the practical applications of neural networks technology, and contains a number of exercises interested Applications to help the student to understand these applications are well known. This book has been arranged to allow the reader walks applications without examining the book's allowed to examine the reader walks applications without regard a particular type of infrastructure networks or learning algorithms, and this method may be the best way to allow readers to compare the work of different structures for networks, although it caused an overlap repeatedly in the book's contents. The book consists of nine chapters.
