During a two-month period, Halley Lee developed two Jupyter Notebooks for the halley1116/2025_DA_study repository, focusing on data analysis and natural language processing. In January, Halley built an exploratory data analysis notebook for insurance data, implementing data loading, descriptive statistics, and analysis of relationships between medical and lifestyle factors using Python and pandas. In February, Halley delivered a sentiment analysis workflow that included data preprocessing, visualization with word clouds, and integration of FastText and logistic regression models. The work emphasized reproducibility and extensibility, providing a solid foundation for future analytics and model experimentation without reported bug fixes.
