Consistency Models for Scalable and Fast Simulation-Based Inference

Marvin Schmitt, Valentin Pratz, Ullrich Köthe +2

Simulation-based inference (SBI) is constantly in search of more expressive and efficient algorithms to accurately infer the parameters of complex simulation models. In line with t…
