Overview of this book

Natural Language Processing (NLP) is the subfield in computational linguistics that enables computers to understand, process, and analyze text. This book caters to the unmet demand for hands-on training of NLP concepts and provides exposure to real-world applications along with a solid theoretical grounding. This book starts by introducing you to the field of NLP and its applications, along with the modern Python libraries that you'll use to build your NLP-powered apps. With the help of practical examples, you’ll learn how to build reasonably sophisticated NLP applications, and cover various methodologies and challenges in deploying NLP applications in the real world. You'll cover key NLP tasks such as text classification, semantic embedding, sentiment analysis, machine translation, and developing a chatbot using machine learning and deep learning techniques. The book will also help you discover how machine learning techniques play a vital role in making your linguistic apps smart. Every chapter is accompanied by examples of real-world applications to help you build impressive NLP applications of your own. By the end of this NLP book, you’ll be able to work with language data, use machine learning to identify patterns in text, and get acquainted with the advancements in NLP.

Architectural forms of RNNs

In this section, we will begin by taking a look into what forms an RNN can take, depending on the application it is being built for. After that, we will dive into bidirectional RNNs, and, finally, we'll end this section by looking into how RNNs can be stacked to build deep RNNs.

Different flavors of RNN

RNNs can take multiple forms, depending on the type of use case it is applied to. Let's see the various forms an RNN can take, as follows:

  • One-to-one: This is the simplest form of RNN and is very similar to a traditional neural network, wherein the RNN takes in a single input and provides a single output. An example of a one-to-one RNN is shown in the following figure:
  • One-to-many: In a one-to-many RNN, the network takes in only one input and produces multiple outputs. Such an RNN is used for solving problems such as music generation, wherein music is generated on the input of a single musical note. An example of a one-to-many RNN is shown in the...
