New methods tackle flow matching with missing data and uncertainty

Researchers have developed a new method called Missing-Data Flow Matching to address the challenge of training generative models with incomplete datasets. This approach treats missing data points as latent variables and averages the loss over their possible values, proving that the correction is exact. Another paper explores the geometric nature of flow matching uncertainty, proposing a cost-free proxy called denoising acceleration ($\mathrm{accel}$) that measures trajectory bending to identify untrustworthy actions without additional training or computation.

    Flow Matching with Missing Data

    arXiv:2607.28698v1 Announce Type: new Abstract: Flow matching assumes fully observed training data, which many real-world applications rarely provide. We propose Missing-Data Flow Matching, which treats the missing coordinates of training samples as latent variables and averages …

    The Geometric Nature and a Free Proxy for Flow-Matching Uncertainty

    Flow matching (FM) has become a popular action head paradigm for modern embodied models. However, as a conditional generative model, it does not explicitly expose its inherent uncertainty, producing faulty action chunks even when it misinterprets the scene or encounters out-of-di…
