Simulation-Based Inference with ML: A Framework Overview

Maximilian Dax, Theo Heimel, Gilles Louppe· July 27, 2026 View original

Summary

This paper provides an introductory overview of simulation-based inference (SBI) using machine learning, detailing its application within both Bayesian and frequentist statistical frameworks. It explains how methods like neural posterior estimation and neural likelihood estimation can solve inverse problems, parameter inference, and unfolding tasks, while also discussing validation and limitations.

Simulation-based inference (SBI) combined with machine learning is becoming an indispensable tool for tackling inverse problems across various scientific and engineering disciplines. These problems often involve inferring underlying parameters from observed data or correcting for detector effects. This paper offers a comprehensive introduction to this powerful methodology. The overview covers how SBI methods, particularly those leveraging machine learning like neural posterior estimation and neural likelihood estimation, can be effectively applied within both Bayesian and frequentist statistical paradigms. It illustrates their utility not only for parameter inference but also for more specialized tasks such as Empirical Bayes and unfolding. Beyond explaining the core techniques, the paper also delves into crucial practical considerations. It discusses essential strategies for validating the results obtained from SBI and highlights the inherent limitations of using machine learning for simulation-based inference, providing a balanced perspective for practitioners.
