Contributed to the scicloj/noj repository by enhancing data provisioning and documentation to support data-driven modeling workflows. Added two key datasets, BicycleWeather.csv and Fremont_Bridge_Bicycle_Counter.csv, using CSV and Clojure to enable linear regression analysis and facilitate repeatable experiments. Improved documentation quality by fixing a duplicated URL in the linear regression introduction notebook, ensuring accurate references for users. Focused on data analysis, data engineering, and link management to accelerate model development and provide reliable training data. The work established a foundation for future analytical tasks, emphasizing maintainability and accessibility of both datasets and supporting documentation within the project.
