Classifying Images with Deep Convolutional Neural Networks

In the previous chapter, we looked in depth at different aspects of the PyTorch neural network and automatic differentiation modules, you became familiar with tensors and decorating functions, and you learned how to work with torch.nn. In this chapter, you will now learn about convolutional neural networks (CNNs) for image classification. We will start by discussing the basic building blocks of CNNs, using a bottom-up approach. Then, we will take a deeper dive into the CNN architecture and explore how to implement CNNs in PyTorch. In this chapter, we will cover the following topics:

Convolution operations in one and two dimensions
The building blocks of CNN architectures
Implementing deep CNNs in PyTorch
Data augmentation techniques for improving the generalization performance
Implementing a facial CNN classifier for recognizing if someone is smiling or not
