Abstract:Abstract-This article presents the results of using neural networks for the optimization of the ATLAS online filterring system, one of the main detectors of the particle collider LHC (Large Hadron Collider). The Regions of Interests of the ATLAS energy measurer calorimeter are mapped in 100 rings of energy deposition, whitch feed a classifier neural network to classify them as electron or jet. For the signal pre-processing, it is used a relevance mapping and PCA (Principal Component Analysis) to compact the in… Show more
