Samsung NNTrainer Contributions

Memory-efficient training features and optimizer support contributed to an open-source training framework.

I contributed a set of training-efficiency improvements to Samsung NNTrainer as an open-source project.

Highlights

  • Implemented gradient checkpointing, reducing training memory usage by up to 46%.
  • Added the Sophia and Lion optimizers to broaden the lightweight optimizer stack.
  • Focused on improvements that are useful under practical compute and memory constraints.
