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.

Basic Atari gaming bot


In this chapter, we are trying a hands-on approach to building some basic gaming bots. We are choosing some famous Atari games that nearly everybody has played at some point in their lives. We choose Atari games because we know how to play them, and that makes our life easy because we can understand what kind of action our bot should perform in order to get better over a period of time.

In this section, we are building our own game. This game is simple, so we can look at how we can apply the Q-Learning algorithms. Here, we will be designing the game world on our own. Let's begin!

Understanding the key concepts

In this section, we will be looking at a lot of important aspects that will help us while coding, so here, we will be covering the following topics:

  • Rules for the game

  • Understanding the Q-Learning algorithm

Rules for the game

Before we begin with the basic concepts or algorithms, we need to understand the rules of the game that we are building. The game is simple and...
