Diffusion Modulation via Environment Mechanism Modeling for Planning
Conventional diffusion models for offline Reinforcement Learning (RL) struggle with inconsistent trajectory generation, failing to align with real-world environment mechanisms. This leads to inaccurate planning and suboptimal policies. Our novel approach, Diffusion Modulation via Environment Mechanism Modeling (DMEMM), directly integrates RL-specific transition dynamics and reward functions into the diffusion model's training process. By modulating the diffusion loss with cumulative rewards and introducing auxiliary losses based on learned environment models, DMEMM ensures generated trajectories are not only plausible but also reward-optimized and transition-coherent. This significantly bridges the gap between simulated and real-world performance, achieving state-of-the-art results across diverse RL planning tasks.

Offline RL Challenges
Offline Reinforcement Learning (RL) aims to train agents from static datasets without environment interaction. A key challenge is the distributional shift between the offline data and the online execution environment, leading to poor generalization. Conventional methods often struggle with out-of-distribution actions, where policies may suggest actions not seen in the training data, resulting in unpredictable or unsafe outcomes. Ensuring policy conservativeness and learning effective strategies from limited, pre-collected data remains a significant hurdle for robust offline planning.
Diffusion Models in RL
Diffusion models, originally for image synthesis, are emerging as powerful tools for trajectory generation and planning in RL. They learn to iteratively refine noisy data into coherent sequences, making them suitable for synthesizing action-state trajectories. In RL, this involves generating sequences that are both plausible (realistic) and optimal (high-reward). However, direct application often overlooks the unique sequential consistency and causal relationships inherent in RL environments, leading to generated trajectories that may not align with real-world dynamics.
DMEMM Methodology
DMEMM addresses these limitations by modulating diffusion model training with explicit RL environment mechanisms. It introduces a reward-aware diffusion loss, weighting trajectories by their cumulative reward to prioritize high-value plans. Additionally, two auxiliary modulation losses – transition-based and reward-based – regularize the process, enforcing consistency with learned dynamics and reward functions. During planning, a dual-guidance mechanism (combining reward and transition models) further refines trajectory generation, ensuring both optimality and environmental fidelity.
Performance & Impact
Our experimental results on D4RL locomotion and Maze2D navigation tasks demonstrate DMEMM's state-of-the-art performance. It significantly outperforms previous diffusion-based and model-free methods, achieving higher average scores and substantial point improvements across various difficulty levels. DMEMM's ability to generate more consistent, reward-optimized trajectories not only enhances planning efficacy but also provides a robust framework for adapting advanced generative models to the nuanced demands of offline RL, paving the way for more reliable and performant AI agents.

Impact on Complex Navigation: Maze2D
Challenge: Traditional methods struggle with long-horizon planning and coherence in complex navigation tasks like Maze2D, often generating suboptimal paths or failing to reach targets efficiently.
Solution: DMEMM's integration of transition dynamics and reward functions ensures that generated trajectories respect environmental constraints and optimize for path efficiency. The dual guidance mechanism during sampling helps in navigating intricate environments more effectively.
Results: DMEMM achieves significant improvements in Maze2D environments, including a 4.0-point gain on U-Maze and a 2.6-point gain on Medium-sized mazes over the previous state-of-the-art (HD-DA). It also shows an almost 20-point improvement over the standard Diffuser method, demonstrating superior performance in generating coherent and efficient navigation plans for enterprise robots or autonomous systems.
