Autoencoders for Real-Time SUEP Detection

no code implementations23 Jun 2023 Simranjit Singh Chhibra, Nadezda Chernyavskaya, Benedikt Maier, Maurzio Pierini, Syed Hasan

A deep convolutional neural autoencoder network has been trained using QCD events by taking transverse energy deposits in the inner tracker, electromagnetic calorimeter, and hadron calorimeter sub-detectors as 3-channel image data.

Anomaly Detection

Triggering Dark Showers with Conditional Dual Auto-Encoders

no code implementations22 Jun 2023 Luca Anzalone, Simranjit Singh Chhibra, Benedikt Maier, Nadezda Chernyavskaya, Maurizio Pierini

We present a search formulated as an anomaly detection (AD) problem, using an AE to define a criterion to decide about the physics nature of an event.

Anomaly Detection

Automated visual inspection of CMS HGCAL silicon sensor surface using an ensemble of a deep convolutional autoencoder and classifier

no code implementations9 Mar 2023 Sonja Grönroos, Maurizio Pierini, Nadezda Chernyavskaya

More than a thousand 8" silicon sensors will be visually inspected to look for anomalies on their surface during the quality control preceding assembly into the High-Granularity Calorimeter for the CMS experiment at CERN.

Anomaly Detection

Lorentz group equivariant autoencoders

1 code implementation14 Dec 2022 Zichun Hao, Raghav Kansal, Javier Duarte, Nadezda Chernyavskaya

There has been significant work recently in developing machine learning (ML) models in high energy physics (HEP) for tasks such as classification, simulation, and anomaly detection.

Anomaly Detection

Evaluating generative models in high energy physics

2 code implementations18 Nov 2022 Raghav Kansal, Anni Li, Javier Duarte, Nadezda Chernyavskaya, Maurizio Pierini, Breno Orzari, Thiago Tomei

There has been a recent explosion in research into machine-learning-based generative modeling to tackle computational challenges for simulations in high energy physics (HEP).

End-to-end multi-particle reconstruction in high occupancy imaging calorimeters with graph neural networks

no code implementations4 Apr 2022 Shah Rukh Qasim, Nadezda Chernyavskaya, Jan Kieseler, Kenneth Long, Oleksandr Viazlo, Maurizio Pierini, Raheel Nawaz

We present an end-to-end reconstruction algorithm to build particle candidates from detector hits in next-generation granular calorimeters similar to that foreseen for the high-luminosity upgrade of the CMS detector.
