During November 2024, Pissca developed an end-to-end PCA dimensionality reduction notebook for the HUFS-DAT/2024-2_Seminar repository, focusing on Fashion MNIST analysis. Using Python and Jupyter Notebook, they implemented a workflow that loads image data, performs tensor conversion and normalization, and applies principal component analysis with multiple component settings. The notebook reports explained variance ratios and reconstruction errors, providing quantitative insight into dimensionality reduction choices. By including 2D visualizations of reduced representations, Pissca enabled more effective exploratory data analysis and feature engineering. The work demonstrates depth in data preprocessing, dimensionality reduction, and image processing, supporting reproducibility and onboarding.

Nov 1, 2024November 2024: Delivered an end-to-end PCA dimensionality reduction notebook for Fashion MNIST analysis in HUFS-DAT/2024-2_Seminar. The notebook loads Fashion MNIST, performs tensor conversion and normalization, and runs PCA with 50, 30, and 2 components. It reports explained variance ratios and reconstruction error and includes a 2D visualization of the reduced representations. This work enhances exploratory data analysis, accelerates feature engineering decisions, and supports model selection with quantitative variance capture. The feature was committed as 4fb638db1d73a05ed14ee00741eb0989c6e54765 (Add files via upload).
