Last time we used ANN to train a Deep Learning model for image recognition using MNIST dataset. This time we are going to look at more advanced network called Convolutional Neural Network or CNN in short.

CNN is designed to tackle image recognition problem. However, it can be used not only for image recognition. As we have seen last time, ANN using just hidden layers can learn quite well on MNIST. However, for real life use cases we need higher accuracy. The main idea of CNN is to learn how to recognise object in their different shapes and positions using specific features of the image data. The goal of CNN is better model regularisation by using convolution and pooling operations.
