Overview of this book

Convolutional Neural Networks (CNN) are one of the most popular architectures used in computer vision apps. This book is an introduction to CNNs through solving real-world problems in deep learning while teaching you their implementation in popular Python library - TensorFlow. By the end of the book, you will be training CNNs in no time! We start with an overview of popular machine learning and deep learning models, and then get you set up with a TensorFlow development environment. This environment is the basis for implementing and training deep learning models in later chapters. Then, you will use Convolutional Neural Networks to work on problems such as image classification, object detection, and semantic segmentation. After that, you will use transfer learning to see how these models can solve other deep learning problems. You will also get a taste of implementing generative models such as autoencoders and generative adversarial networks. Later on, you will see useful tips on machine learning best practices and troubleshooting. Finally, you will learn how to apply your models on large datasets of millions of images.

Chapter 1. Setup and Introduction to TensorFlow

TensorFlow is an open source software library created by Google that allows you to build and execute data flow graphs for numerical computation. In these graphs, every node represents some computation or function to be executed, and the graph edges connecting up nodes represent the data flowing between them. In TensorFlow, the data is multi-dimensional arrays called Tensors. Tensors flow around the graph, hence the name TensorFlow.

Machine learning (ML) models, such as convolutional neural networks, can be represented with these kinds of graphs, and this is exactly what TensorFlow was originally designed for.

In this chapter, we'll cover the following topics:

  • Understanding the TensorFlow way of thinking
  • Setting up and installing TensorFlow
  • Introduction to TensorFlow API levels
  • Building and training a linear classifier in TensorFlow
  • Evaluating a trained model
