For deep learning enthusiasts, working with the MNIST dataset is the equivalent of writing the "hello world" program when learning a new scripting language like Python, JavaScript etc. In this project, I experiment with the vast and highly dimensional hyperparameter space using the MNIST dataset.

About the MNIST dataset

The Modified National Institute of Standards and Technology (MNIST) dataset comprises 60000 images of handwritten numbers. All images are in greyscale and have a pixel size of 28 (height) by 28 (width). The M in the MNIST dataset indicates that it was created from the original NIST dataset and can be considered a subset of the NIST dataset. It currently serves as a good database for machine learning enthusiasts to learn different classification and learning models without having to bother with the complexities of data cleaning and data generally preprocessing.

Experiment

This project aims to explore the systematic, incremental changes to the hyperparameters in getting the optimal performance of the models built during the experiment. This process, commonly referred to as hyperparameters optimisation, focuses on fine-tuning models to generalise better on unseen data, which is usually the essence of modelling.
