Diagnosing JEPA World Models with Action-Conditioned Predictive Consistency
Action-Conditioned Predictive Consistency (ACPC), a diagnostic that measures how far a clean history and a visually perturbed view of it diverge after being rolled forward under the same action sequence, is introduced and it is proved that this divergence bounds the perturbation-induced change in multi-step prediction error and planner cost.
