Practical Big Data Analytics

By: Nataraj Dasgupta

Overview of this book

Big Data analytics relates to the strategies used by organizations to collect, organize, and analyze large amounts of data to uncover valuable business insights that cannot be analyzed through traditional systems. Crafting an enterprise-scale cost-efficient Big Data and machine learning solution to uncover insights and value from your organization’s data is a challenge. Today, with hundreds of new Big Data systems, machine learning packages, and BI tools, selecting the right combination of technologies is an even greater challenge. This book will help you do that. With the help of this guide, you will be able to bridge the gap between the theoretical world of technology and the practical reality of building corporate Big Data and data science platforms. You will get hands-on exposure to Hadoop and Spark, build machine learning dashboards using R and R Shiny, create web-based apps using NoSQL databases such as MongoDB, and even learn how to write R code for neural networks. By the end of the book, you will have a very clear and concrete understanding of what Big Data analytics means, how it drives revenues for organizations, and how you can develop your own Big Data analytics solution using the different tools and methods articulated in this book.

Preface

Chapter 8. Machine Learning Deep Dive

The prior chapter on machine learning provided a preliminary overview of the subject, including the different classes and core concepts in the subject area. This chapter will delve deeper into the theoretical aspects of machine learning such as the limits of algorithms and how different algorithms work.

Machine learning is a vast and complex subject, and to that end, this chapter focuses on the breadth of different topics, rather than the depth. The concepts are introduced at a high level and the reader may refer to other sources to further their understanding of the topics.

We will start out by discussing a few fundamental theories in machine learning, such as Gradient Descent and VC Dimension. Next, we will look at Bias and Variance, two of the most important factors in any modelling process and the concept of bias-variance trade-off.

We'll then discuss the various machine learning algorithms, their strengths and areas of applications.

We'll conclude with...
