The mass of neutrinos and their oscillation behavior remain one of the most complex and unresolved problems in modern nuclear and particle physics. The Jiangmen Underground Neutrino Observatory (JUNO) is a major international scientific experiment designed specifically to address these issues. By determining the hierarchy of neutrino masses, the project is expected to significantly advance our understanding of particle physics and the Standard Model.This paper focuses on the application of artificial intelligence—particularly, an autoencoder model—for detecting rare signals observed in the JUNO experiment. This approach has proven effective in identifying infrequent but scientifically important events that might otherwise be missed. Autoencoders, as unsupervised learning models, enhance the ability to detect anomalies and extract meaningful patterns from large-scale experimental data. It is important to note that JUNO is not merely a study of subatomic particles. Rather, it represents a scientific journey toward uncovering the deeper mysteries of the universe. Sometimes, the quietest and most unassuming signals may hold the key to the most fundamental laws of nature.
