Align & Invert: Solving Inverse Problems with Diffusion and Flow-based Models via Representational Alignment

arXiv — cs.LGMonday, November 24, 2025 at 5:00:00 AM
  • A recent study has introduced a method called representation alignment (REPA) to enhance the performance of diffusion and flow-based generative models in solving inverse problems. By aligning the internal representations of these models with those of pretrained self-supervised encoders like DINOv2, the reconstruction process at inference time is significantly improved, even in the absence of ground-truth signals.
  • This development is crucial as it provides a robust framework for improving the fidelity and perceptual realism of reconstructions in inverse problems, which are common in various fields such as imaging and signal processing. The ability to leverage pretrained models as priors can lead to advancements in applications requiring high-quality reconstructions.
  • The integration of representation alignment reflects a growing trend in artificial intelligence where the synergy between generative models and self-supervised learning is being explored. This approach not only enhances model performance but also aligns with broader efforts in the AI community to improve the interpretability and efficiency of machine learning systems, addressing challenges in areas like visual emotion recognition and dynamic imaging.
