Training My Neural Network with the MNIST (Handwritten Digits) Dataset

I trained my neural network with the MNIST dataset in this project. The MNIST dataset consists of handwritten images (60,000 images in the training set and 10,000 images in the test set). (Link to Github Repo of Source Code).

The neural network with forward propagation and back-propagation pass is implemented in The MyImg2Num neural network is defined in It relies on the Neural Network class implemented in for its functionality. The NnImg2Num neural network is defined in This neural network uses the torch.nn neural network package for its functionality. Finally both of these neural networks are trained and tested on the MNIST handwritten digits dataset. In order to run the scripts, simply create an instance of the corresponding class and call the train() instance method as shown below.

nn_mnist = NnImg2Num()


my_mnist = MyImg2Num()


The performance charts associated with each of the neural networks are given below.
