The world is on the verge of fully ushering in the fourth industrial revolution, of which artificial intelligence (AI) is the most important general-purpose technology. AI is the theory and development of machines that can imitate human intelligence in tasks such as visual perception, speech recognition, decision-making, and human language translation. In this book, the authors will present state-of-the-art AI applications and research with a focus on machine learning and deep learning applications, and Deep neural network architectures. This book will provide a complete overview of AI and deep learning technologies and applications with the future work overview.
