Cognitive Neuroscience of Natural Language Use

by Roel M. Willems

When we think of everyday language use, the first things that come to mind include colloquial conversations, reading and writing e-mails, sending text messages or reading a book. But can we study the brain basis of language as we use it in our daily lives? As a topic of study, the cognitive neuroscience of language is far removed from these language-in-use examples. However, recent developments in research and technology have made studying the neural underpinnings of naturally occurring language much more feasible. In this book a range of international experts provide a state-of-the-art overview of current approaches to making the cognitive neuroscience of language more 'natural' and closer to language use as it occurs in real life. The chapters explore topics including discourse comprehension, the study of dialogue, literature comprehension and the insights gained from looking at natural speech in neuropsychology.

Cognitive Plausibility in Natural Language Processing (Synthesis Lectures on Human Language Technologies)

by Lisa Beinborn Nora Hollenstein

This book explores the cognitive plausibility of computational language models and why it’s an important factor in their development and evaluation. The authors present the idea that more can be learned about cognitive plausibility of computational language models by linking signals of cognitive processing load in humans to interpretability methods that allow for exploration of the hidden mechanisms of neural models. The book identifies limitations when applying the existing methodology for representational analyses to contextualized settings and critiques the current emphasis on form over more grounded approaches to modeling language. The authors discuss how novel techniques for transfer and curriculum learning could lead to cognitively more plausible generalization capabilities in models. The book also highlights the importance of instance-level evaluation and includes thorough discussion of the ethical considerations that may arise throughout the various stages of cognitive plausibility research.

Cognitive Radio Mobile Ad Hoc Networks

by F. Richard Yu

Cognitive radios (CR) technology is capable of sensing its surrounding environment and adapting its internal states by making corresponding changes in certain operating parameters. CR is envisaged to solve the problems of the limited available spectrum and the inefficiency in the spectrum usage. CR has been considered in mobile ad hoc networks (MANETs), which enable wireless devices to dynamically establish networks without necessarily using a fixed infrastructure. The changing spectrum environment and the importance of protecting the transmission of the licensed users of the spectrum mainly differentiate classical MANETs from CR-MANETs. The cognitive capability and re-configurability of CR-MANETs have opened up several areas of research which have been explored extensively and continue to attract research and development. The book will describe CR-MANETs concepts, intrinsic properties and research challenges of CR-MANETs. Distributed spectrum management functionalities, such as spectrum sensing and sharing, will be presented. The design, optimization and performance evaluation of security issues and upper layers in CR-MANETs, such as transport and application layers, will be investigated.

Cognitive Risk (Security, Audit and Leadership Series)

by James Bone Jessie H Lee

Cognitive Risk is a book about the least understood but most pervasive risk to mankind – human decision-making. Cognitive risks are subconscious and unconscious influence factors on human decision-making: heuristics and biases. To understand the scope of cognitive risk, we look at case studies, corporate and organizational failure, and the science that explains why we systemically make errors in judgment and repeat the same errors. The book takes a multidisciplinary and pedestrian stroll through behavioral science with a light touch, using stories to explain why we consistently make cognitive errors that not only increase risks but also simultaneously fail to recognize these errors in ourselves or our organizations. This science has deep roots in organizational behavior, psychology, human factors, cognitive science, and behavioral science all influenced by classic philosophers and enabled through advanced analytics and artificial intelligence. The point of the book is simple. Humans persist with bounded rationality, but as the speed of information, data, money, and life in general accelerates, we will need the right tools to not only keep pace but to survive and thrive. In light of all these factors that complicate risk, the book offers a foundational solution. A cognitive risk framework for enterprise risk management and cyber security. There are five pillars in a cognitive risk framework with five levels of maturity, yet there is no universally prescribed maturity level. It is more a journey of different paths. Each organization will pursue its own path, but the goal is the same – to minimize the errors that could have been avoided. We explain why risks are hard to discuss and why we systematically ignore the aggregation of these risks hidden in collective decision-making in an organization. The cognitive risk framework is a framework designed to explore the two most complex risks organizations face: uncertainty and decision-making under uncertainty. The first pillar is cognitive governance, which is a structured approach for institutionalizing rational decision-making across the enterprise. Each pillar is complimentary and builds on the next in a succession of continuous learning. There is no endpoint because the pillars evolve with technology. Enterprise risk is a team effort in risk intelligence grounded in a framework for good decision-making. We close with a call to become designers of risk solutions enabled by the right technology and nurtured by collaboration. We hope you enjoy the book with this context.
