arXiv:2601.22443v2 Announce Type: replace Abstract: Can a diffusion model trained on bedrooms recover human faces? Diffusion models are widely used as priors for inverse problems, but standard approaches usually assume a high-fidelity model trained on data that closely match the unknown signal. In practice, one often must use a mismatched or low-fidelity diffusion prior. Surprisingly, these weak priors often perform nearly as well as full-strength, in-domain baselines. We study when and why inverse solvers are robust to weak diffusion priors. Through extensive experiments, we find that weak pr
The rapid advancement and widespread adoption of diffusion models for generative AI and inverse problem solving necessitate a deeper understanding of their robustness when confronted with practical limitations such as mismatched or low-fidelity training data.
This research reveals the surprising robustness of inverse solvers utilizing 'weak' diffusion priors, implying that generative AI models might be more versatile and less constrained by perfect domain-specific training than previously assumed.
The findings suggest that the resource requirements for training highly effective diffusion models for specific inverse problems might be lower, opening doors for broader application and potentially reducing the compute burden.

Less stringent data requirements for diffusion model application in inverse problems will accelerate deployment in various fields.
This could lead to a proliferation of more generalized AI models capable of solving a wider array of tasks with less specialized training.
Reduced dependence on highly specialized datasets might democratize access to advanced AI capabilities, fostering innovation in resource-constrained environments.
