Qinchuan Zhang developed notebook-based sentiment analysis workflows for the Open-Finance-Lab/FinLLM-Leaderboard repository, focusing on reproducible experimentation and streamlined onboarding. Using Python, Jupyter Notebooks, and the OpenAI API, Zhang created test and tutorial notebooks that enable authentication, inference, evaluation, and robust error handling for the o3-mini model. The work emphasized reliable performance metrics such as macro-F1 and accuracy, while implementing retry and checkpointing features to support experiment reproducibility. In addition, Zhang improved user experience by cleaning up notebook UI, simplifying Colab onboarding, and removing outdated or extraneous code, resulting in a more maintainable and accessible workflow.

Month: 2025-10 — Focused on improving user experience and maintainability of the FinLLM-Leaderboard notebook workflow. Delivered targeted UI cleanup and Colab onboarding simplifications for the FPB_TestByChatGPT_o3_mini.ipynb, accompanied by a code/doc cleanup to reduce noise and maintenance overhead. The changes streamline Colab usage and reduce setup friction for new users, contributing to faster onboarding and lower support cost. All work centralized in a cohesive feature in Open-Finance-Lab/FinLLM-Leaderboard.
