Overview of this book

Learning how to solve natural language processing (NLP) problems is an important skill to master due to the explosive growth of data combined with the demand for machine learning solutions in production. Natural Language Processing with TensorFlow, Second Edition, will teach you how to solve common real-world NLP problems with a variety of deep learning model architectures. The book starts by getting readers familiar with NLP and the basics of TensorFlow. Then, it gradually teaches you different facets of TensorFlow 2.x. In the following chapters, you then learn how to generate powerful word vectors, classify text, generate new text, and generate image captions, among other exciting use-cases of real-world NLP. TensorFlow has evolved to be an ecosystem that supports a machine learning workflow through ingesting and transforming data, building models, monitoring, and productionization. We will then read text directly from files and perform the required transformations through a TensorFlow data pipeline. We will also see how to use a versatile visualization tool known as TensorBoard to visualize our models. By the end of this NLP book, you will be comfortable with using TensorFlow to build deep learning models with many different architectures, and efficiently ingest data using TensorFlow Additionally, you’ll be able to confidently use TensorFlow throughout your machine learning workflow.

Understanding CNNs

Now that we understand the high level concepts governing CNNs, let’s walk through the technical details of a CNN. First, we will discuss the convolution operation and introduce some terminology, such as filter size, stride, and padding. In brief, filter size refers to the window size of the convolution operation, stride refers to the distance between two movements of the convolution window, and padding refers to the way you handle the boundaries of the input. We will also discuss an operation that is known as deconvolution or transposed convolution. Then we will discuss the details of the pooling operation. Finally, we will discuss how to add fully connected layers, which produce the classification or regression output.

Convolution operation

In this section, we will discuss the convolution operation in detail. First, we will discuss the convolution operation without stride and padding, then we will describe the convolution operation with stride, and...
