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 set up the coding environment for the face recognition application. We will look at how to install dependencies. We will be installing the following two libraries:

  • dlib

  • face_recognition

Let's begin the installation process.

Installing dlib

In order to install the dlib library, we need to perform the following steps. We can install this library either on a Linux operating system (OS), or on macOS. Let's follow the stepwise instructions:

  1. Download the source code of dlib by executing this command:

    sudo git clone https://github.com/davisking/dlib.git.
  2. Now jump to the dlib directory by executing this command: cd dlib.

  3. Now we need to build the main dlib library, so we need to execute the following commands stepwise:

    1. sudo mkdir build.

    2. cd build.

    3. cmake .. -DDLIB_USE_CUDA=0 -DUSE_AVX_INSTRUCTIONS=1.

    4. cmake --build.

Once the project has been built successfully, you can move to the next installation steps. You also need to install OpenCV. The installation...
