Preface

Although artificial neural networks (ANNs) have been around for decades, they have only begun to be used in fields such as health care, energy management, supply chains, inventory management, and transportation due to unprecedented advances in information and communication technologies.

This book explores the potential of ANNs for applications in different fields. It includes eight chapters that discuss deep learning, ANN tools, and other cutting-edge technologies. It also suggests avenues for further research into ANN techniques for medical imaging to detect breast tumors, classification of COVID-19 surveillance datasets, health management, estimation of materials processing parameters, solar energy management, and control of a petrochemical unit.
