In this chapter, we introduced you to ML and artificial intelligence. We looked at what artificial neural networks are and how to train them. After this, we looked at CNNs and their main building blocks. We explained how to use TensorFlow to train your own CNN for recognizing digits. Finally, we had an introduction to Tensorboard and saw how it can be used to help visualize important statistics while training models in TensorFlow.

In the next chapter, we are going to look more closely at the task of image classification and how we can use CNNs and TensorFlow to solve this task.
