Understanding the MNIST dataset

Modified National Institute of Standards and Technology (MNIST) is a dataset that contains images of handwritten digits. This dataset is pretty popular in the ML community for implementing and testing computer vision algorithms. The MNIST dataset is an open dataset made available by Professor Yann LeCun at http://yann.lecun.com/exdb/mnist/, where separate files that represent the training dataset and test dataset are available. The labels corresponding to the test and training datasets are also available as separate files. The training dataset has 60,000 samples and the test dataset has 10,000 samples.

The following diagram shows some sample images from the MNIST dataset. Each of the images also comes with a label indicating the digit shown in the following screenshot:
