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 list down the libraries and equipment you need in order to run the upcoming code. You need to have a webcam that can at least stream the video with good clarity. We will be using OpenCV, TensorFlow, YOLO, Darkflow, and Darknet libraries. I'm not going to explain how to install TensorFlow, because it is an easy process and you can find the documentation for the installation by clicking on https://www.tensorflow.org/install/install_linux.

In this section, we will be looking at how to set up OpenCV first and, in the upcoming sections, we will see how to set up YOLO, Darkflow, and DarkNet.

Setting up and installing OpenCV

OpenCV stands for Open Source Computer Vision. It is designed for computational efficiency, with a strong focus on real-time applications. In this section, you will learn how to set up OpenCV. I'm using Ubuntu 16.04 and I have a GPU, so I have already installed CUDA and CUDNN. If you haven't installed CUDA and CUDNN,...
