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

Image Augmentation

Augmentation is defined as making something better by making it greater in size or amount. This is exactly what data or image augmentation does. You use augmentation to provide the model with more versions of your image training data. Remember that the more data you have, the better the model's performance will be. By augmenting your data, you can transform your images in a way that makes the model generalize better on real data. To do this, you transform the images that you have at your disposal so that you can use your augmented images alongside your original image dataset to train with a greater variation and variety than you would have otherwise. This improves results and prevents overfitting. Take a look at the following three images:

Figure 7.14: Augmented leopard images

It's clear that this is the same leopard in all three images. They're just in different positions. Neural networks can still make sense of this due to...
