Preface
This book introduces the fundamental concepts of different tools and techniques related to Data Science that are widely used in a variety of applications such as statistical analytics, business data analytics, social media analytics, and big data analytics. Topics covered in the book include fundamentals of Data Science, data preprocessing, data plotting and visualization, statistical data analysis, machine learning for data analysis, time-series analysis, deep learning for Data Science, social media analytics, business analytics, and big data analytics. The content of each Chapter describes the fundamentals together with how various data analysis techniques can be implemented using different tools and libraries of Python programming language.
Readers with previous knowledge of python programming will find it easy to understand the program examples presented in the chapters. Each chapter contains numerous examples and illustrative output that explains the important concepts. An appropriate number of questions is presented at the end of each chapter for self-assessing the conceptual understanding. The references presented at the end of every chapter will help the readers to explore more on a given topic.Over the ten chapters in this book, you will learn the following:
Chapter 1 discusses the various aspects of Data science, such as the importance and need of Data Science in today’s marketing trend. The main discussions covered in this Chapter are the complete life cycle of data analytics, the various types of data analytics, and the major tools required for data analysis. Coverage of the role of SQL in Data Science has been provided, as well as the various pros and cons of studying Data Science are explained to understand the current demand of this area of study. All the topics discussed in this Chapter are crucial to be learned by a reader for exploring Data science and for building a career in Data Science, which is and will remain as one of the most demanding careers till the next few decades.
Chapter 2 gives a brief introduction to data preprocessing and its need for data analytics. The various data types and the possible error types that occur on data are also discussed in detail. Various standard data preprocessing operations are elaborately explained, starting from data cleaning, data integration, data transformation, data reduction, and data discretization. For each data preprocessing method, simple examples are provided, and the corresponding Python code is given to demonstrate how the preprocessing operation works.
Chapter 3 gives a detailed explanation of the importance of data plotting and data visualization in data analytics. The importance and use of various data visualization graphs have been discussed. Several basic, specialized, and advanced visualization tools and the corresponding libraries used for each tool have been covered in detail. For each visualization tool, illustrative examples with well-explained Python code and corresponding output are also provided. This chapter covers an important concept of Data Science as the findings in a visualization graph may be subtle, yet it can create a profound impact on a data analyst to interpret the information easily.
Chapter 4 introduces the importance of statistics in data analysis. The chapter starts with the role of statistics in data analysis, and then it elaborately discusses the two main kinds of statistics commonly used for data analysis, namely the descriptive statistics and the inferential statistics. The chapter also introduces probability theory and explains the various concepts related to probability theory. The later part of the chapter discusses Bayesian probability and provides illustrations and Python code for the same.
Chapter 5 discusses in detail the concepts of machine learning used for data analysis. The chapter initially introduces the concept of machine learning and its primary role in data analysis. The various machine learning techniques that have evolved and established their presence in data analytics, such as supervised learning, unsupervised learning, and reinforcement learning, have been discussed in detail in the chapter.
Chapter 6 starts with an overview of time-series analysis and also discusses the important characteristics of time-series data. The latest standard time-series models are discussed along with the mathematical foundations and corresponding related illustrative examples. Each of the time-series modeling techniques is also explained using appropriate Python programs to correlate the applicability of the theory to applications.
Chapter 7 gives an overview of Deep learning relating to Data Science. The prerequisite concepts of deep learning are elaborately discussed here. The chapter also broadly explains the two main deep learning techniques that are widely used for data analysis, namely the Convolutional Neural Network and the AutoEncoder. Each of the deep learning techniques is explained using appropriate Python programs to correlate the applicability of the theory to applications.
Chapter 8 gives a detailed overview of social media analytics and emphasizes the impact of data and analytics on social media. Social media data is huge and highly dynamic and unstructured. The chapter discusses how such data on social media can be extracted for further analysis. It also explains the various important analyses carried out for social media data such as social network analysis, text analysis, and trend analysis.
Chapter 9 introduces to readers an overview of business analytics and its role in making decisions for businesses. The m
