Artificial intelligence (AI) is "the study and design of intelligent agents", where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. In this book, the authors present recent advances in the study of artificial intelligence with topics that include a Twitter specific lexicon for sentiment analysis; hybrid unsupervised-supervised artificial neural networks for modeling activated sludge wastewater treatment plants; fast and visible trajectory planning in 3D urban environments based on local point clouds data; and "smart brakes" - the neuro-genetic optimization of brake actuation pressure.
