Jiyoon Kim developed robust data analysis and preprocessing solutions in the HUFS-DAT/2024-2_Seminar repository, focusing on reproducibility and analytical depth. They built a PCA-based Jupyter Notebook for Fashion MNIST, applying multi-component dimensionality reduction and visualizing results with Matplotlib and Seaborn to enhance interpretability. Kim also improved reliability in baseball analytics notebooks by correcting file paths and standardizing preprocessing for metrics like woba. In December, they delivered an end-to-end data preparation pipeline for the model1 dataset, implementing missing value checks, correlation analysis, and scaling using Pandas and Scikit-learn, which streamlined data quality and accelerated experimental workflows.

November 2024 performance highlights focused on delivering a reproducible, analytics-ready environment in HUFS-DAT/2024-2_Seminar. Key features delivered a PCA-based image data notebook for Fashion MNIST with multi-component PCA, variance analysis, reconstruction error, and label-colored 2D visualization, enabling deeper dimensionality reduction experiments. Major fixes addressed notebook reliability in Baseball Analytics by correcting file paths, execution counts, and preprocessing/model parameters for metrics like woba and exit_velocity_avg. Collectively, these efforts improved data exploration capabilities, reliability, and onboarding for analysts, with tangible business value in faster insights and more robust analytics pipelines.
