SHared autonomy is becoming increasingly important in complex and information rich systems. THe purpose of shared autonomy is to exploit the human cognitive abilities in complex missions. It has been evident that the information overload in these complex missions has a detrimental effect on the human performance. THe focus of this talk is the design of efficient shared autonomy. It is imperative for such designs to efficiently handle information overload and to effectively integrate human cognition into shared autonomy.
In this talk, I will focus on three important aspects of these designs. First, I will focus on modeling human decision-making in tasks involving exploration-exploitation trade-off using the context of multiarmed bandit problems. I will present a model for decision-making in such tasks that captures behavioral data and has provable performance. I will show how the model can be leveraged in engineering design. Second, I will discuss how cognitive models can be integrated in engineering analysis and design. I will integrate a model of human decision making in tasks involving speed-accuracy trade-off and integrate it with a popular model for information assimilation in social networks to analyze decision-making in so-called socio-cognitive networks. I will identify influence of network structure in decision-making performance. Finally, I will focus on information-overload problem in shared autonomy. I will show that optimization problems associated with handling information overload problem are non-convex and will design efficient algorithms for these problems.
