The Gaussian Is Enough: Flow-Matching Priors Do Not Help When Fine-Tuning Large Behavior Models
Simpler probabilistic foundations outperform complex alternatives in robotic imitation learning tasks.
Modern robot imitation learning increasingly relies on generative policies based on diffusion or flow-matching models, which generate actions by transforming samples from a prior distribution. A key question is whether the choice of prior matters. Replacing the standard Gaussian ...

This research suggests that the complexity of flow-matching priors is often unnecessary for training high-performance robotic policies. By confirming that simple Gaussian distributions suffice, engineers can significantly reduce computational overhead during behavior model fine-tuning.
