Trust-Aware Planning: Modeling Trust Evolution in Iterated Human-Robot Interaction

no code implementations3 May 2021 Zahra Zahedi, Mudit Verma, Sarath Sreedharan, Subbarao Kambhampati

The problem of trust management is particularly challenging in mixed human-robot teams where the human and the robot may have different models about the task at hand and thus may have different expectations regarding the current course of action, thereby forcing the robot to focus on the costly explicable behavior.


A Unifying Bayesian Formulation of Measures of Interpretability in Human-AI

Recent work in explanation generation for decision making agents has looked at how unexplained behavior of autonomous systems can be understood in terms of differences in the model of the system and the human's understanding of the same, and how the explanation process as a result of this mismatch can be then seen as a process of reconciliation of these models.
