Curiosity-Critic reward improves world model training accuracy

Researchers have introduced a novel intrinsic reward mechanism called Curiosity-Critic for training world models. This method grounds its reward in the improvement of the world model's cumulative prediction error, offering a tractable per-step surrogate. A learned critic estimates the error baseline online, guiding exploration towards learnable transitions and distinguishing between reducible and irreducible prediction errors. Experiments demonstrated that Curiosity-Critic surpasses existing methods in training speed and world model accuracy. AI

    Curiosity-Critic: Cumulative Prediction Error Improvement as a Tractable Intrinsic Reward for World Model Training

    arXiv:2604.18701v2 Announce Type: replace-cross Abstract: Local prediction-error-based curiosity rewards focus on the current transition without considering the world model's cumulative prediction error across all visited transitions. We introduce Curiosity-Critic, which grounds …
