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.

Setting up the coding environment


In this section, we will cover how to set up a coding environment that can help us implement our applications. We need to install the gym library. These are the steps that you can follow. I'm using Ubuntu 16.04 LTS as my operating system:

  • Step 1: Clone the gym repository from GitHub by executing this command: $ sudo git clone https://github.com/openai/gym.gi t

  • Step 2: Jump to the gym directory by executing this command: $ cd gym

  • Step 3: Execute this command to install the minimum number of required libraries for gym: $ sudo pip install -e

  • Step 4: Install the gaming environment for Atari games by executing this command: $ sudo pip install gym[atari]

  • Step 5: This step is optional. If you want to install all the gaming environments, then you can execute the following commands:

    • $ sudo apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb libav-tools xorg-dev python-opengl libboost-all-dev libsdl2-dev swig

    • $ sudo pip install gym[all]...
