"Recurrent dynamical systems have become fundamental models that describe complex behaviour in a wide range of fields. Such systems can be found in the study of oscillators, population dynamics, climate fluctuations, control theory, neural networks design, and efficient continuous-time learning models for Artificial Intelligence. Cognitive properties of complex oscillators have been intensively investigated in the past few years due to them being considered as potential avenues to accelerate the execution of deep neural networks. This book builds on these topics through intuitive descriptions of fundamental concepts together with mathematical models, simulations, and experimental verifications"--
