Effects of Providing End-User Feedback on User Perceptions of Human-in-the-Loop Systems

Establishing the effects of providing human-in-the-loop feedback on user perceptions and behavior in differing contexts, showing negative effects on trust and system perceptions when providing objective feedback and positive effects when providing reasoning-based feedback.

First Impressions & Trust Calibration in Explainable AI

IUI 2021 Best Paper Honorable Mention

A DARPA XAI study on how explanations from a dynamic cutset network affect trust in video activity recognition. Evaluation shows that early impressions of an AI system's mistakes anchor users' trust well after true accuracy becomes clear.
