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.

Movie recommendations

Recommendation systems play a major role in the discovery process for a user. Think of an e-commerce catalog that has thousands of distinct products. Additionally, variants of a product also exist. In such cases, educating the user about the products or events (in case certain products are on sale) becomes the key to increasing sales.

Getting ready

In this recipe, we will be learning about building a recommendation system for a database of ratings given by users to movies. The objective of the exercise is to maximize the relevance of a movie to a user. While defining the objective, we should also consider that a movie that is recommended might still be relevant, but might not be watched by the user immediately...
