Dive into Learning From Data using the famous MNIST dataset. Explore the classical Logistic Regression algorithm, a simple yet powerful method, and aim to achieve an almost perfect score on MNIST. We review the fundamentals, analyze the data, and evaluate performance metrics. Finally, we apply dimensionality reduction (PCA) and feature engineering (Polynomial Features) to boost performance, achieving an impressive 98.05% accuracy.
