Overview of this book

Deep Learning with TensorFlow and Keras teaches you neural networks and deep learning techniques using TensorFlow (TF) and Keras. You'll learn how to write deep learning applications in the most powerful, popular, and scalable machine learning stack available. TensorFlow 2.x focuses on simplicity and ease of use, with updates like eager execution, intuitive higher-level APIs based on Keras, and flexible model building on any platform. This book uses the latest TF 2.0 features and libraries to present an overview of supervised and unsupervised machine learning models and provides a comprehensive analysis of deep learning and reinforcement learning models using practical examples for the cloud, mobile, and large production environments. This book also shows you how to create neural networks with TensorFlow, runs through popular algorithms (regression, convolutional neural networks (CNNs), transformers, generative adversarial networks (GANs), recurrent neural networks (RNNs), natural language processing (NLP), and graph neural networks (GNNs)), covers working example apps, and then dives into TF in production, TF mobile, and TensorFlow with AutoML.

A summary of convolution operations

In this section, we present a summary of different convolution operations. A convolutional layer has I input channels and produces O output channels. I x O x K parameters are used, where K is the number of values in the kernel.

Basic CNNs

Let’s remind ourselves briefly what a CNN is. CNNs take in an input image (two dimensions), text (two dimensions), or video (three dimensions) and apply multiple filters to the input. Each filter is like a flashlight sliding across the areas of the input, and the areas that it is shining over are called the receptive field. Each filter is a tensor of the same depth of the input (for instance, if the image has a depth of three, then the filter must also have a depth of three).

When the filter is sliding, or convolving, around the input image, the values in the filter are multiplied by the values of the input. The multiplications are then summarized into one single value. This process is repeated...
