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.

Introduction

RNN can be architected in multiple ways. Some of the possible ways are as follows:

The box in the bottom is the input, followed by the hidden layer (as the middle box), and the box on top is the output layer. The one-to-one architecture is the typical neural network with a hidden layer between the input and the output layer. The examples of different architectures are as follows:

Architecture Example
One-to-many Input is image and output is caption of image
Many-to-one Input is a movie's review (multiple words in input) and output is sentiment associated with the review
Many-to-many Machine translation of a sentence in one language to a sentence in another language
