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

Deep Convolutional Generative Adversarial Networks (DCGANs)

DCGANs use convolutional neural networks instead of simple neural networks for both the discriminator and the generator. They can generate higher-quality images and are commonly used for this purpose.

The generator is a set of convolutional layers with fractional stride convolutions, also known as transpose convolutions. Layers with transpose convolutions upsample the input image at every convolutional layer, which increases the spatial dimensions of the images after each layer.

The discriminator is a set of convolutional layers with stride convolutions, so it downsamples the input image at every convolutional layer, decreasing the spatial dimensions of the images after each layer.

Consider the following two images. Can you identify which one is fake and which one is real? Take a moment and look carefully at each of them.
