Robust Posterior Diffusion-based Sampling via Adaptive Guidance Scale

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A new approach called Adaptive Posterior diffusion Sampling (AdaPS) has been proposed to enhance diffusion models for solving inverse problems in imaging. This method introduces an adaptive likelihood step-size strategy that balances prior contributions with data fidelity, aiming to improve reconstruction quality without the need for hyperparameter tuning.
  • The development of AdaPS is significant as it addresses a critical challenge in generative modeling, particularly in achieving optimal reconstructions while minimizing artifacts. This advancement could lead to more efficient and effective applications in various imaging tasks.
  • The introduction of AdaPS aligns with ongoing efforts in the AI field to refine generative models, particularly in areas like face de-identification. Techniques such as FLUID, which utilizes pretrained diffusion models for identity substitution, highlight a growing trend towards enhancing privacy and identity management in AI-generated content.

EnfoPath: Energy-Informed Analysis of Generative Trajectories in Flow Matching
NeutralArtificial Intelligence
A new study titled 'EnfoPath: Energy-Informed Analysis of Generative Trajectories in Flow Matching' introduces kinetic path energy (KPE) as a diagnostic tool for evaluating flow-based generative models. The research reveals that higher KPE correlates with stronger semantic quality in generated samples, indicating that richer samples require more kinetic effort. Additionally, it finds that informative samples tend to exist in low-density regions of the data space.
FLUID: Training-Free Face De-identification via Latent Identity Substitution
PositiveArtificial Intelligence
FLUID introduces a training-free framework for face de-identification that substitutes identity in the latent space of pretrained diffusion models, achieving a balance between identity suppression and attribute preservation. Experimental results on datasets like CelebA-HQ and FFHQ indicate its superiority over existing methods in both qualitative and quantitative metrics.
