PROFILE

Zichongli5

Developed and integrated the NorMuon optimizer for distributed training within the microsoft/dion repository, focusing on improving convergence, scalability, and reliability for large-scale deep learning workflows. Leveraged Python and PyTorch to implement momentum support, adaptive learning rates, and muon-based enhancements, enabling faster and more stable training across sharded configurations. Enhanced the optimizer with robust exception handling for unsupported sharding dimensions, reducing training-time failures and maintenance risk. Streamlined performance by removing legacy functions and integrating new library features, which facilitated easier onboarding for contributors. The work laid a foundation for efficient experimentation and cost-effective production training in distributed machine learning environments.
