Image Classification on the MNIST Dataset Using Keras This article assumes you have intermediate or better programming skill with a C-family language and a basic familiarity with machine learning but ...

Dr. James McCaffrey of Microsoft Research details the 'Hello World' of image classification: a convolutional neural network (CNN) applied to the MNIST digits dataset.

An example of visualization of the MNIST classification outcome using CNN models is shown in Fig 2 below (See visualization at front end here).
