Record completeness
Claims
We identify the minimal perturbations to the recorded observations needed for the expert's actions to appear optimal. We develop a practical algorithm for this problem and demonstrate its utility for quantifying the possible extent of missing observations in behavioral datasets through extensive experiments on synthetic navigation tasks, a cancer treatment simulator, and ICU treatment data.
That the minimal perturbations identified correspond to plausible unobserved observations available to the original decision-maker and that standard IRL optimality assumptions hold once those observations are restored.
A practical algorithm quantifies potential missing observations in IRL by computing minimal perturbations to recorded data that render expert actions optimal.
