Overview of this book

Getting to grips with tensors, deep learning, and neural networks can be intimidating and confusing for anyone, no matter their experience level. The breadth of information out there, often written at a very high level and aimed at advanced practitioners, can make getting started even more challenging. If this sounds familiar to you, The TensorFlow Workshop is here to help. Combining clear explanations, realistic examples, and plenty of hands-on practice, it’ll quickly get you up and running. You’ll start off with the basics – learning how to load data into TensorFlow, perform tensor operations, and utilize common optimizers and activation functions. As you progress, you’ll experiment with different TensorFlow development tools, including TensorBoard, TensorFlow Hub, and Google Colab, before moving on to solve regression and classification problems with sequential models. Building on this solid foundation, you’ll learn how to tune models and work with different types of neural network, getting hands-on with real-world deep learning applications such as text encoding, temperature forecasting, image augmentation, and audio processing. By the end of this deep learning book, you’ll have the skills, knowledge, and confidence to tackle your own ambitious deep learning projects with TensorFlow.

Preface

Object Classification

In this section, you will learn about object detection and classification. The next step involves image classification for a dataset with more than two classes. The three different types of models for object classification we will cover are image classification, classification with localization, and detection:

  • Image classification: This involves training with a set number of classes and then trying to determine which of those classes is shown in the image. Think of the MNIST handwriting dataset. For these problems, you'll use a traditional CNN.
  • Classification with localization: With this type, the model tries to predict where the object is in the image space. For these models, you use a simplified You Only Look Once (YOLO) or R-CNN.
  • Detection: The last type is detection. This is where your model can detect several different objects and where they are located. For this, you use YOLO or an R-CNN:
