Overview of this book

<p>Computer vision is one of today's most exciting application fields of Machine Learning, From self-driving cars to Medical diagnosis, this has been widely used in various domains.</p> <p>This course will take you right from the essential concepts of statistical learning to help you with various algorithms to implement it with other OpenCV tasks.</p> <p>The course will also guide you through creating custom graphs and visualizations, and show you how to go from the raw data to beautiful visualizations. We will also build a machine learning system that can make a medical diagnosis.</p> <p>By the end of this course, you will be ready create your own ML system and will also be able to take on your own machine learning problems.</p> <p>All the code and supporting files for this course are available on Github at <a style="color: #fa8d11;" href="https://github.com/PacktPublishing/Machine-Learning-for-OpenCV-Supervised-Learning" target="blank">https://github.com/PacktPublishing/Machine-Learning-for-OpenCV-Supervised-Learning</a></p> <h2>Style and Approach</h2> <p>This course walks you through the key elements of OpenCV and its powerful Machine Learning classes while demonstrating how to get to grips with a range of models.</p>

Representing Categorical Variables and Text Features
In this video, we will learn to represent data using categorical features also known as discrete features. Then we also look at representing any word or a phrase as numerical value using text features. - Execute a program to encode a dataset consisting of a list of forefathers of machine learning and artificial intelligence - Consider a dataset that contains a small corpus of text phrases - store feature matrix X as a sparse matrix
