Researchers have developed a novel method called Critic-Guided Synthetic Experience (CGSE) to enhance learning from offline datasets in world models. This approach uses the world model as a local transition generator, employing critic guidance to select actions within the model and create synthetic experiences. CGSE augments existing datasets by refining candidate actions to maximize the Q-function within a trust region, then using the world model to predict future states and select the optimal transition. This technique generates synthetic experience offline without requiring new real-world interactions or a test-time planner, leading to a 7.1% improvement in average success rate on OGBench manipulation tasks.
