Uncertainty-Aware Distribution-to-Distribution Flow Matching for Scientific Imaging

arXiv:2603.21717v4 Announce Type: replace Abstract: Distribution-to-distribution generative models support scientific imaging tasks ranging from modeling cellular perturbation responses to translating medical images across conditions. Trustworthy generation requires reliability, or generalization across labs, devices, and experimental conditions, and accountability, or detecting out-of-distribution cases where predictions may be unreliable. We leverage Stochastic Flow Matching (SFM), a marginal-preserving stochastic extension of flow matching for improved generalization under distribution shif

Why this matters
Why now

The increasing complexity and regulatory scrutiny of AI in critical applications like scientific and medical imaging necessitate more robust, trustworthy, and accountable generative models capable of handling real-world data variability.

Why it’s important

This development addresses key limitations in AI's reliability and generalization, particularly in fields where 'trustworthy generation' is paramount, thereby expanding AI's practical deployment in sensitive domains.

What changes

AI generative models can now better account for uncertainty and generalize across diverse experimental conditions, leading to more reliable and accountable predictions in scientific and medical imaging applications.
