Overview of this book

Machine learning (ML) helps you find hidden insights from your data without the need for explicit programming. This book is your key to solving any kind of ML problem you might come across in your job. You’ll encounter a set of simple to complex problems while building ML models, and you'll not only resolve these problems, but you’ll also learn how to build projects based on each problem, with a practical approach and easy-to-follow examples. The book includes a wide range of applications: from analytics and NLP, to computer vision domains. Some of the applications you will be working on include stock price prediction, a recommendation engine, building a chat-bot, a facial expression recognition system, and many more. The problem examples we cover include identifying the right algorithm for your dataset and use cases, creating and labeling datasets, getting enough clean data to carry out processing, identifying outliers, overftting datasets, hyperparameter tuning, and more. Here, you'll also learn to make more timely and accurate predictions. In addition, you'll deal with more advanced use cases, such as building a gaming bot, building an extractive summarization tool for medical documents, and you'll also tackle the problems faced while building an ML model. By the end of this book, you'll be able to fine-tune your models as per your needs to deliver maximum productivity.

Chapter 11. Building Gaming Bot

In previous chapters, we covered applications that belong to the computer vision domain. In this chapter, we will be making a gaming bot. We will cover different approaches to build the gaming bot. These gaming bots can be used to play a variety of Atari games.

Let's do a quick recap of the past two years. Let's begin with 2015. A small London-based company called DeepMind published a research paper titled Playing Atari with Deep Reinforcement Learning, available at https://arxiv.org/abs/1312.5602 In this paper, they demonstrated how a computer can learn and play Atari 2600 video games. A computer can play the game just by observing the screen pixels. Our computer game agent (the computer game player) will receive rewards when the game score increases. The result presented in this paper is remarkable. The paper created a lot of buzz, and that was because each game has different scoring mechanisms and these games are designed in such a way that humans find it...
