Researchers have developed a new diagnostic tool called Action-Conditioned Predictive Consistency (ACPC) to evaluate world models within Joint-embedding predictive architectures (JEPAs). ACPC measures how much a world model's predictions diverge when presented with visually perturbed inputs compared to clean inputs, under identical action sequences. This metric is shown to bound prediction errors caused by visual perturbations and helps assess the distinguishability of different states after rollouts. Experiments on various visual control tasks demonstrate ACPC's effectiveness in predicting changes in prediction and cost errors, and its diagnostic capabilities across different perturbation types.
