In recent years fully-parametric fast simulation methods based on generative models have been proposed for a variety of high-energy physics detectors.

Towards Reliable Neural Generative Modeling of Detectors

no code implementations21 Apr 2022 Lucio Anderlini, Matteo Barbetti, Denis Derkach, Nikita Kazeev, Artem Maevskiy, Sergei Mokhnenko

The increasing luminosities of future data taking at Large Hadron Collider and next generation collider experiments require an unprecedented amount of simulated events to be produced.

Machine Learning on sWeighted Data

no code implementations17 Oct 2019 Maxim Borisyak, Nikita Kazeev

Data analysis in high energy physics has to deal with data samples produced from different sources.

Fast Data-Driven Simulation of Cherenkov Detectors Using Generative Adversarial Networks

no code implementations28 May 2019 Artem Maevskiy, Denis Derkach, Nikita Kazeev, Andrey Ustyuzhanin, Maksim Artemev, Lucio Anderlini

The increasing luminosities of future Large Hadron Collider runs and next generation of collider experiments will require an unprecedented amount of simulated events to be produced.

Machine Learning on data with sPlot background subtraction

1 code implementation28 May 2019 Maxim Borisyak, Nikita Kazeev

In this paper we propose a mathematically rigorous way to train machine learning algorithms on data samples with background described by sPlot to obtain signal probabilities conditioned on observables, without encountering negative event weight at all.

Cherenkov Detectors Fast Simulation Using Neural Networks

no code implementations28 Mar 2019 Denis Derkach, Nikita Kazeev, Fedor Ratnikov, Andrey Ustyuzhanin, Alexandra Volokhova

We propose a way to simulate Cherenkov detector response using a generative adversarial neural network to bypass low-level details.
