Offline Reinforcement Learning with Generative Trajectory Policies

arXiv:2510.11499v2 Announce Type: replace Abstract: Generative models have emerged as a powerful class of policies for offline reinforcement learning (RL) due to their ability to capture complex, multi-modal behaviors. However, existing methods face a stark trade-off: slow, iterative models like diffusion policies are computationally expensive, while fast, single-step models like consistency policies often suffer from degraded performance. In this paper, we demonstrate that it is possible to bridge this gap. The key to moving beyond the limitations of individual methods, we argue, lies in a un

Why this matters
Why now

The continuous evolution of AI research and the increasing demand for more efficient and performant reinforcement learning models drive this optimization for generative policies.

Why it’s important

This development could significantly enhance the capabilities of AI systems, particularly in autonomous decision-making and complex behavioral modeling, by making generative RL more practical.

What changes

The trade-off between speed and performance in offline reinforcement learning using generative models is being addressed, potentially enabling wider adoption in real-world applications.
