New work challenges how JEPA decides which world-model features to keep
ShahabBakht · x · 2026-10-23
A research thread examines how JEPA selects which features its world model keeps. Prior work suggested that, judged feature by feature, JEPA would drop features it cannot predict (like a traffic light changing). The authors present evidence that this is wrong and introduce a new characterization explaining why.
