The intelligence demonstrated by machines is known as artificial intelligence, or AI. Several capabilities of modern machines such as understanding human speech effectively and operating cars autonomously are classified as artificial intelligence. There are 3 types of systems into which artificial intelligence can be categorized- analytical, human inspired and humanized. Analytical artificial intelligence only possesses characteristics from cognitive intelligence. Human inspired artificial intelligence combines elements from both cognitive and emotional intelligence. Humanized artificial intelligence is self-aware and is able to show attributes of cognitive, social and emotional intelligence. There are several tools used in AI such as artificial neural networks, search and mathematical optimization and methods based on probability, economics, statistics etc. This book unfolds the innovative aspects of artificial intelligence which will be crucial for the progress of this field in the future. The topics included herein are of utmost significance and bound to provide incredible insights to readers. This book will serve as a valuable source of reference for graduate and post graduate students.
