What Machine Learning Can Do for Focusing Aerogel Detectors

no code implementations5 Dec 2023 Foma Shipilov, Alexander Barnyakov, Vladimir Bobrovnikov, Sergey Kononov, Fedor Ratnikov

Particle identification at the Super Charm-Tau factory experiment will be provided by a Focusing Aerogel Ring Imaging CHerenkov detector (FARICH).

Energy reconstruction for large liquid scintillator detectors with machine learning techniques: aggregated features approach

no code implementations17 Jun 2022 Arsenii Gavrikov, Yury Malyshkin, Fedor Ratnikov

Large-scale detectors consisting of a liquid scintillator target surrounded by an array of photo-multiplier tubes (PMTs) are widely used in the modern neutrino experiments: Borexino, KamLAND, Daya Bay, Double Chooz, RENO, and the upcoming JUNO with its satellite detector TAO.

Generative Adversarial Networks for LHCb Fast Simulation

no code implementations21 Mar 2020 Fedor Ratnikov

LHCb is one of the major experiments operating at the Large Hadron Collider at CERN.

$(1 + \varepsilon)$-class Classification: an Anomaly Detection Method for Highly Imbalanced or Incomplete Data Sets

1 code implementation14 Jun 2019 Maxim Borisyak, Artem Ryzhikov, Andrey Ustyuzhanin, Denis Derkach, Fedor Ratnikov, Olga Mineeva

We explore a novel method that gives a trade-off possibility between one-class and two-class approaches, and leads to a better performance on anomaly detection problems with small or non-representative anomalous samples.
