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.

The optimal action to take in a simulated game with a non-negative reward

In this section, we will understand the way in which we can take the right action for a simulated game. Note that this exercise will primarily help you to grasp how reinforcement learning works.

Getting ready

Let's define the environment we are operating in this simulated setting.

You have three boxes, on which two players are playing a game. Player 1 marks a box with 1 and player 2 marks one with 2. The player who is able to mark two consecutive boxes wins.

The empty board for this game looks as follows:

For the problem we just defined, only player 1 has an opportunity to win the game. The possible scenarios in which player 1 wins are either...
