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.

Building the baseline model


In this section, we will be looking at the coding part. You can refer to the code given at this GitHub link: https://github.com/jalajthanaki/Real_time_object_detection/tree/master/base_line_model.

First, download the project from the given link and install OpenCV, as per the information given earlier in this chapter. When you download this project folder, there is a pre-trained MobileNet SSD that has been implemented using the caffe library, but here, we are using the pre-trained binary model. We are using OpenCV for loading the pre-trained model as well as streaming the video feeds from the webcam.

In the code, first, we specify the libraries that we need to import and define the command-line arguments that will be used to run the script. We need to provide the parameter file and the pre-trained model. The name of the parameter file is MobileNetSSD_deploy.prototxt.txt and the filename for the pre-trained model is MobileNetSSD_deploy.caffemodel. We have also defined...
