Researchers have developed a new protocol called the "fork ledger" to measure the actual value of updates to world models in continual learning scenarios. This method branches a deployment stream at specific points, allowing for a direct comparison between applying an update and holding the model's parameters constant. Experiments on control tasks like CartPole, Walker, and Cheetah showed that consistently applying updates, even with a fixed mechanism, can decrease performance. AI
