Classifiers are becoming an important component of today software. The capability of automatic learning from examples is essential in tasks where classification rules are not easily obtainable. Artificial Neural Networks, the main argument of this book, are an important example of classifiers for their versatility and recognition accuracy. To improve their classification performance the easiest way is to enlarge the training databases. Unfortunately, this method leads to training times too much long. In this book, Artificial Neural Networks are firstly presented in deep, with details to...
