Comparative Analysis of Dimensionality Reduction Techniques on Fashion-MNIST
A comprehensive comparison of three dimensionality reduction techniques — PCA, t-SNE, and UMAP — applied to the Fashion-MNIST dataset (3,000 samples). The analysis covers quantitative evaluation (silhouette scores, k-NN preservation, retrieval precision, confusion analysis), advanced experiments (cluster density, embedding stability, distance preservation), and real-world application analogies. Interactive scatter plots with hover-to-view-image functionality are included for exploratory visualization.
