PROFILE

Sharmistha Chakrabarti

Sourabh Chakrabarti contributed to the lanl/Yoke repository by delivering three features over three months, focusing on machine learning workflows and code quality. He enhanced test coverage for the Swin Transformer encoder’s MLP class using Python, PyTorch, and Pytest, reorganizing the test suite for maintainability and clarity. In time-series modeling, he implemented scheduled sampling for LodeRunner training, improving sequential data learning and reducing exposure bias, while expanding dataset utilities and validating results with robust tests. Additionally, he streamlined experiment execution by introducing a symbolic link for study scripts, leveraging filesystem operations and Python to improve workflow efficiency and reproducibility.
