Overview of this book

Julia is a fast and high performing language that's perfectly suited to data science with a mature package ecosystem and is now feature complete. It is a good tool for a data science practitioner. There was a famous post at Harvard Business Review that Data Scientist is the sexiest job of the 21st century. (https://hbr.org/2012/10/data-scientist-the-sexiest-job-of-the-21st-century). This book will help you get familiarised with Julia's rich ecosystem, which is continuously evolving, allowing you to stay on top of your game. This book contains the essentials of data science and gives a high-level overview of advanced statistics and techniques. You will dive in and will work on generating insights by performing inferential statistics, and will reveal hidden patterns and trends using data mining. This has the practical coverage of statistics and machine learning. You will develop knowledge to build statistical models and machine learning systems in Julia with attractive visualizations. You will then delve into the world of Deep learning in Julia and will understand the framework, Mocha.jl with which you can create artificial neural networks and implement deep learning. This book addresses the challenges of real-world data science problems, including data cleaning, data preparation, inferential statistics, statistical modeling, building high-performance machine learning systems and creating effective visualizations using Julia.

Preface

Summary


In this chapter, we learned about machine learning and its uses. Providing computers the ability to learn and improve has far-reaching uses in this world. It is used in predicting disease outbreaks, predicting weather, games, robots, self-driving cars, personal assistants, and much more.

There are three different types of machine learning: supervised learning, unsupervised learning, and reinforcement learning.

In this chapter, we learned about supervised learning, especially about Naïve Bayes and decision trees. In further chapters, we will learn more about ensemble learning and unsupervised learning.
