Researchers have developed a new Simulation-Based Inference (SBI) framework designed to tackle the computational challenges of profiling systematic uncertainties in high-dimensional data analyses. This novel approach utilizes Factorizable Normalizing Flows to model systematic variations as parametric deformations, preserving complex correlations and avoiding combinatorial explosions. An amortized training strategy enables the framework to learn conditional dependencies efficiently, and a Poisson-bootstrap ensemble provides a comprehensive uncertainty budget. The method has been validated on a synthetic dataset, demonstrating its potential to extend rigorous unbinned likelihood measurements to differential distributions and unify various analytical tasks in high-energy physics.
