  Data Scientist Intern

  Global Artificial Intelligence Accelerator (GAIA), Team NEUTRON 2 (Manager: Dr. Wenting Sun)Develop a novel graph neural network (GNN-based) root cause analysis (RCA) algorithm that is applicable to 5G wireless environments. The goal is to predict potential root cause nodes and a chain of failures led by the root cause nodes. Higher prediction accuracy is achieved in our simulation if more nodes (features) are considered.
