Practical Convolutional Neural Networks

Practical example – image classification

The convolutional layer helps to detect regional patterns in an image. The max pooling layer, present after the convolutional layer, helps reduce dimensionality. Here is an example of image classification using all the principles we studied in the previous sections. One important notion is to first make all the images into a standard size before doing anything else. The first convolution layer requires an additional input.shape() parameter. In this section, we will train a CNN to classify images from the CIFAR-10 database. CIFAR-10 is a dataset of 60,000 color images of 32 x 32 size. These images are labeled into 10 categories with 6,000 images each. These categories are airplane, automobile, bird, ...
