A new research paper proposes a method called "differential retention" for world models in machine learning. Unlike traditional continual learning, which treats forgetting as a failure, this approach acknowledges that world models must adapt to changing environments. The paper argues for stratifying knowledge retention based on invariance timescales, distinguishing between fundamental principles like physics that should never be revised and instance-level facts that should be updated. This method aims to better evaluate world models by assessing their ability to revise outdated information while preserving core invariants, addressing limitations in current metrics that favor frozen models.
