Overview of this book

This book will take you from the basics of neural networks to advanced implementations of architectures using a recipe-based approach. We will learn about how neural networks work and the impact of various hyper parameters on a network's accuracy along with leveraging neural networks for structured and unstructured data. Later, we will learn how to classify and detect objects in images. We will also learn to use transfer learning for multiple applications, including a self-driving car using Convolutional Neural Networks. We will generate images while leveraging GANs and also by performing image encoding. Additionally, we will perform text analysis using word vector based techniques. Later, we will use Recurrent Neural Networks and LSTM to implement chatbot and Machine Translation systems. Finally, you will learn about transcribing images, audio, and generating captions and also use Deep Q-learning to build an agent that plays Space Invaders game. By the end of this book, you will have developed the skills to choose and customize multiple neural network architectures for various deep learning problems you might encounter.

Generating text

In the sentiment-classification recipes that we performed in Chapter 11, Building a Recurrent Neural Network, we were trying to predict a discrete event (sentiment classification). This falls under the many-to-one architecture. In this recipe, we will learn how to implement a many-to-many architecture, where the output would be the next possible 50 words of a given sequence of 10 words.

Getting ready

The strategy that we'll adopt to generate text is as follows:

  1. Import project Gutenberg's Alice's Adventures in Wonderland dataset, which can be downloaded from https://www.gutenberg.org/files/11/11-0.txt.
  1. Preprocess the text data so that we bring every word to the same case, and remove punctuation...
