Coupled Data Generation and Transfer
WOMBET proposes a unified framework that overcomes the limitations of existing offline-to-online RL methods by jointly generating and utilizing prior data. Instead of assuming a fixed, pre-existing dataset, WOMBET actively constructs reliable experience from a source task. This iterative process refines both the world model and the policy, enabling a dynamic and adaptive learning cycle.
Uncertainty-Aware Planning and Filtering
At the heart of WOMBET is its ability to learn a world model in the source task. This model is then used for uncertainty-penalized planning to generate offline data. A crucial dual-criterion filter ensures that only trajectories with high return and low epistemic uncertainty are selected, suppressing bias and creating a high-quality dataset. During online fine-tuning, adaptive sampling balances source (offline) and target (online) data, allowing for a stable and efficient transition.
Superior Sample Efficiency and Robustness
Empirical results demonstrate that WOMBET significantly improves sample efficiency and achieves higher final performance compared to strong baselines on continuous control benchmarks. This is attributed to its ability to leverage prior data effectively, mitigate distributional shifts through adaptive sampling, and maintain stable value estimates via implicit regularization (LayerNorm and ensemble critics). The framework's theoretical grounding provides a provable lower bound on true return, ensuring robust optimization.
