Learning from images

This chapter covers

• Building a feed-forward neural network

• Loading data using Datasets and DataLoaders

• Understanding classification loss

The last chapter gave us the opportunity to dive into the inner mechanics of learning

through gradient descent, and the facilities that PyTorch offers to build models

and optimize them. We did so using a simple regression model of one input and

one output, which allowed us to have everything in plain sight but admittedly was

only borderline exciting.

In this chapter, we’ll keep moving ahead with building our neural network foundations.

This time, we’ll turn our attention to images. Image recognition is arguably

the task that made the world realize the potential of deep learning.
