Detailed Description

Use Simulation Based Inference (SBI) in multiple dimensions in RooFit.

This tutorial shows how to use SBI in higher dimension in ROOT. This tutorial transfers the simple concepts of the 1D case introduced in rf615_simulation_based_inference.py onto the higher dimensional case.

Again as reference distribution we choose a simple uniform distribution. The target distribution is chosen to be Gaussian with different mean values. The classifier is trained to discriminate between the reference and target distribution. We see how the neural networks generalize to unknown mean values.

Furthermore, we compare SBI to the approach of moment morphing. In this case, we can conclude, that SBI is way more sample eficcient when it comes to estimating the negative log likelihood ratio.

For an introductory background see rf615_simulation_based_inference.py
