PCA-on-MNIST

This notebook was developed for my internship at Analytics Vidhya as a part of the study material for their course on Applied Machine Learning in the Advanced Dimensionality Reduction module.

What will we do?

• Train a random forest classifier for digit label prediction on the original dataset
• Transform the data using PCA
• Train the same random forest classifier on the transformed data
• Compare performance before and after PCA

Surprise: Accuracy increases after Dimensionality Reduction!
