Convolutional neural network analysis
Swiss scientists are investigating the use of CNNs to perform the low-level data analysis of Cherenkov telescopes data [arXiv:1907.02428]. The standard γ-hadron separation based on binary decision trees (BDTs) was outperformed under specific conditions. This network was used to process Crab N ebula data of LS T-1 and again the CNNs outperformed the standard analysis. Other networks were trained to reconstruct the energy and origin direction of γ-ray events. CNNs outperformed the standard analysis also for energy reconstruction. Further developments are ongoing.
