arXiv:2512.20685v3 Announce Type: replace-cross Abstract: Diffusion models have recently emerged as powerful learners for simulation-based inference (SBI), enabling fast and accurate estimation of latent parameters from simulated and real data. Their score-based formulation offers a flexible way to learn conditional or joint distributions over parameters and observations, thereby providing a versatile solution to various modeling problems. In this tutorial review, we synthesize recent developments on diffusion models for SBI, covering design choices for training, inference, and evaluation. We
Diffusion models have rapidly advanced, demonstrating capabilities that make them highly relevant for complex estimation problems, specifically in simulation-based inference (SBI). This review synthesizes these recent developments, highlighting their current utility and future potential.
This development is crucial for improving the efficiency and accuracy of scientific discovery, engineering optimization, and AI model development processes across various domains. It provides a versatile tool for understanding complex systems where direct observation is difficult or impossible.
The ability to learn complex conditional and joint distributions is enhanced, leading to more robust and faster estimation of latent parameters in simulation-intensive fields. This could accelerate the development cycle for AI and other scientific applications.
