Summary
I see the emergence of a new discipline, called Cognitive Dynamic Systems, which builds on ideas in statistical signal processing, stochastic control, and information theory, and weaves those well-developed ideas into new ones drawn from neuroscience, statistical learning theory, and game theory. The discipline will provide principled tools for the design and development of a new generation of wireless dynamic systems exemplified by cognitive radio and cognitive radar with efficiency, effectiveness, and robustness as the hallmarks of performance.
This quotation is taken from a point-of-view article that appeared in the Proceedings of the Institute of Electrical and Electronics Engineers (Haykin, 2006a). In retrospect, it is perhaps more appropriate to refer to Cognitive Dynamic Systems as an “integrative field” rather than a “discipline.”
By speaking of cognitive dynamic systems as an integrative field, we mean this in the sense that its study integrates many fields that are rooted in neuroscience, cognitive science, computer science, mathematics, physics, and engineering, just to name a few. Clearly, the mixture of fields adopted in the study depends on the application of interest. However, irrespective of the application, the key question is
What is the frame of reference for justifying that a so-called cognitive dynamic system is indeed cognitive?
In this book, we adopt human cognition as the frame of reference. As for applications, the book focuses on cognitive radar and cognitive radio.
