Description

Determination of neutrino mass ordering and precise measurement of oscillation parameters $\sin^2\theta_{12}$, $\Delta m^2_{21}$ and $\Delta m^2_{31}$ are the main goals of JUNO experiment. A rich physics program such as solar neutrinos, supernova neutrinos, geo-neutrinos, and atmosphere neutrinos is foreseen. The ability to accurately reconstruct events in JUNO is critical to the success of the experiment. In this talk, four machine learning methods applied to the vertex and the energy reconstruction will be presented, including Boosted Decision Trees (BDT), Deep Neural Networks (DNN), Convolution Neural Networks (CNN), and Graph Neural Network (GNN). We demonstrated that machine learning methods can provide the necessary level of accuracy required to achieve JUNO's physical goals: $\sigma_{E}=3\%$ and $\sigma_{x,y,z}=10$ cm at 1 MeV for energy and vertex, respectively.
