This book presents an insight about artificial neural networks (ANNs) which will help researchers/academicians to understand the concept of ANNs in a crisp, clear and easier way. This book covers fundamentals of ANNs in a systemic manner with solved numerical examples. This book also illustrates the implementation of ANNs using MATLAB environment. The real time application examples of ANNs are also presented. I believe that this book will be really a beginners’ guide for undergraduate/postgraduate students and researchers and can also be used as the research manual.
