RADAR-X: An Interactive Interface Pairing Contrastive Explanations with Revised Plan Suggestions
share
Empowering decision support systems with automated planning has received significant recognition in the planning community. The central idea for such systems is to augment the capabilities of the human-in-the-loop with automated planning techniques and provide timely support to enhance the decision-making experience. In addition to this, an effective decision support system must be able to provide intuitive explanations based on specific queries on proposed decisions to its end users. This makes decision-support systems an ideal test-bed to study the effectiveness of various XAIP techniques being developed in the community. To this end, we present our decision support system RADAR-X that extends RADAR (Grover et al. 2020) by allowing the user to participate in an interactive explanatory dialogue with the system. Specifically, we allow the user to ask for contrastive explanations, wherein the user can try to understand why a specific plan was chosen over an alternative (referred to as the foil). Furthermore, we use the foil raised as evidence for unspecified user preferences and use it to further refine plan suggestions.
