Summary

• What is new: AdaFlow introduces a variance-adaptive ODE solver for efficient policy generation in imitation learning, focusing on multi-modal decision-making with quick inference times.
• Why this is important: Diffusion-based imitation learning offers improved decision-making diversity but suffers from slow inference due to its recursive nature.
• What the research proposes: AdaFlow leverages flow-based generative modeling with state-conditioned ODEs to create a policy generator that dynamically adjusts its inference step size for efficient and diverse action generation.
• Results: AdaFlow demonstrates superior performance in terms of success rate, behavioral diversity, and inference speed across various settings, presenting a significant improvement over existing methods.
