Neural networks are systems loosely based on the organisation of neurons in the brain.
Neurons are connected by weighted paths and 'fire' when a threshold is exceeded. The emphasis this time is on a selection of more recent algorithms, some of them in use in commercial systems. However the book is also suitable for someone new to neural networks since clear descriptions of all the ideas and algorithms are presented and much of the material from the earlier book is recapped. If you are also interested in genetic algorithms I should point out that these are not covered by this book, but they are covered well in Practical Neural Network Recipes . The application uses scripts to define a run of a network.
