Modeling Human Behavior Part II -- Cognitive approaches and Uncertainty
It addresses the problem of improving AI systems by incorporating human-like cognitive models, but it is incremental as it builds on prior work in the field.
This paper reviews methods for modeling human behavior by focusing on cognitive abilities, limitations, and biases, such as cognitive architectures and representations of uncertainty, to replicate human reasoning in artificial systems.
As we discussed in Part I of this topic, there is a clear desire to model and comprehend human behavior. Given the popular presupposition of human reasoning as the standard for learning and decision-making, there have been significant efforts and a growing trend in research to replicate these innate human abilities in artificial systems. In Part I, we discussed learning methods which generate a model of behavior from exploration of the system and feedback based on the exhibited behavior as well as topics relating to the use of or accounting for beliefs with respect to applicable skills or mental states of others. In this work, we will continue the discussion from the perspective of methods which focus on the assumed cognitive abilities, limitations, and biases demonstrated in human reasoning. We will arrange these topics as follows (i) methods such as cognitive architectures, cognitive heuristics, and related which demonstrate assumptions of limitations on cognitive resources and how that impacts decisions and (ii) methods which generate and utilize representations of bias or uncertainty to model human decision-making or the future outcomes of decisions.
