Deep Learning for Energy Estimation and Particle Identification in Gamma-ray Astronomy
This work addresses data analysis challenges in gamma-ray astronomy for the TAIGA experiment, but it is incremental as it applies existing deep learning techniques to a specific domain.
The paper tackled gamma-ray event selection and energy estimation in the TAIGA experiment using CNNs, achieving improved selection quality and energy estimation compared to conventional Hillas methods, with GPU redevelopment leading to significantly faster calculations.
Deep learning techniques, namely convolutional neural networks (CNN), have previously been adapted to select gamma-ray events in the TAIGA experiment, having achieved a good quality of selection as compared with the conventional Hillas approach. Another important task for the TAIGA data analysis was also solved with CNN: gamma-ray energy estimation showed some improvement in comparison with the conventional method based on the Hillas analysis. Furthermore, our software was completely redeveloped for the graphics processing unit (GPU), which led to significantly faster calculations in both of these tasks. All the results have been obtained with the simulated data of TAIGA Monte Carlo software; their experimental confirmation is envisaged for the near future.
