Description

Based on ParticleNet, ParticleTransformer, and physics prior knowledge, we modified the model architecture and achieved a significant improvement in performance on the 2024 experimental data of the Crab Nebula. In addition, we explored a semi-supervised learning approach. Using the SimSiam training framework, we performed extensive pretraining on a large amount of experimental data, which helped alleviate the performance degradation caused by the mismatch between Monte Carlo simulations and real experimental data.
