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.

Summary


Congratulations, readers; you have made it to the end! We covered basic concepts related to reinforcement learning in this chapter. You learned about the various concepts and algorithms of building the gaming bot. You also learned how the Deep Q Learner algorithm works. Using the gym library, we loaded the gaming world. By using the dqn library, we will be able to train the model. Training a gaming bot that can defeat human level experts takes a lot of time. So, I trained it for a few hours only. If you want to train for more hours, you can definitely do that. We tried to build a variety of simple Atari games, such as a simple pathfinder gaming bot, Space Invaders, Pong, and Flappy Bird. You can expand this basic approach to the bigger gaming environment. If you want to get yourself updated and contribute, then you can take a look at the OpenAI GitHub repository at: https://github.com/openai.
