Playing with MNIST in C++

Playing with MNIST

Introduction

In this project, we implement a hand-written digit recognizer using C++ and MNIST dataset.

Contents

This project includes multiple contents.

Theoretical Explanations

pdf/mnist.pdf gives theoretical explanations about machine learning, neural networks, and so on.

MNIST Dataset Reader

The codes under read_mnist/ implement a reader for MNIST Dataset which works in C++. You can just pick the directory to embed the reader into your application. See read_mnist/README.md for the detail.

Hand-Written Digit Recognizer

./mnist.cpp and the headers under ./header implement a hand-written digit recognizer. Consult pdf/mnist.pdf for the details about implementations and the code structure.

We also provide a tester recognition_of_user_supplied_data/draw_digit.py in which a user draws a digit using his/her mouse and the true digit the user intended is inferred. See the animation below for a demo.

Demo of draw_digit.py.

Supported Environments

This project is cross-platform; Linux, macOS and Windows are supported.
