Description

Identify rare new physics process through an anomaly detection technique based on deep neural network (Graph Neural Network architecture).

Material for the exercise i.e. datasets and examples have been copied to the leonardo cluster and are available at:
/leonardo/home/usertrain/a08trb55/anomalyDetection/LHCO

Project proposal: description of the problem

Given a (pre-processed) dataset from fast simulation of a generic HEP detector containing a large number of events from Standard Model background processes and a test dataset containing both background and new physics signal events, design and train an anomaly detection model for anomaly detection of the NP processes.

Input dataset

Preprocessed data fro LHC OLYMPIC benchmark dataset, provided as numpy arrays

Machine learning methods

Graph Neural Networks and Auto-Encoder architectures

Goal and FOM

ROC curves, AUC

Project proposal: general context

High Energy Physics NP searches, Graph Neural Networks, Anomaly Detection
