Dealing with Nuisance Parameters using Machine Learning in High Energy Physics: a Review

2020-07-17 · Tommaso Dorigo, Pablo de Castro

In this work we discuss the impact of nuisance parameters on the effectiveness of machine learning in high-energy physics problems, and provide a review of techniques that allow to include their effect and reduce their impact in the search for optimal selection criteria and variable transformations. The introduction of nuisance parameters complicates the supervised learning task and its correspondence with the data analysis goal, due to their contribution degrading the model performances in real data, and the necessary addition of uncertainties in the resulting statistical inference. The approaches discussed include nuisance-parameterized models, modified or adversary losses, semi-supervised learning approaches, and inference-aware techniques.

Orthogonal Machine Learning: Power and Limitations

2017-11-01 · ICML 2018 7 · Lester Mackey, Vasilis Syrgkanis, Ilias Zadik

Double machine learning provides $\sqrt{n}$-consistent estimates of parameters of interest even when high-dimensional or nonparametric nuisance parameters are estimated at an $n^{-1/4}$ rate. The key is to employ Neyman-…

Optimal statistical inference in the presence of systematic uncertainties using neural network optimization based on binned Poisson likelihoods with nuisance parameters

2020-03-16 · Stefan Wunsch, Simon Jörger, Roger Wolf, Günter Quast

Data analysis in science, e.g., high-energy particle physics, is often subject to an intractable likelihood if the observables and observations span a high-dimensional input space. Typically the problem is solved by redu…

Machine Learning-based Unfolding for Cross Section Measurements in the Presence of Nuisance Parameters

2025-12-08 · Huanbiao Zhu, Krish Desai, Mikael Kuusela, Vinicius Mikuni 외 arxiv

Statistically correcting measured cross sections for detector effects is an important step across many applications. In particle physics, this inverse problem is known as unfolding. In cases with complex instruments, the…
