Data-driven and AI-aided applications are next-generation technologies that can be used to visualize and realize intelligent transactions in finance, banking, and business. These transactions will be enabled by powerful data-driven solutions, IoT technologies, AI-aided techniques, data analytics, and visualization tools. To implement these solutions, frameworks will be needed to support human control of intelligent computing and modern business systems. The power and consistency of data-driven competencies are a critical challenge, and so is developing explainable AI (XAI) to make data-driven transactions transparent. Data analytics is the process of examining, cleaning, transforming and interpreting data to uncover meaningful patterns, trends and insights. It involves the use of statistical and computational techniques to analyze data and extract valuable information. Data analytics can be categorized into four main types: descriptive analytics, diagnostic analytics, predictive analytics, and prescriptive analytics. The commonly used tools and applications in data analytics include the following: • Excel: Microsoft Excel is a widely used tool for data analysis due to its user-​friendly interface and familiar spreadsheet format. • SQL: Structured Query Language (SQL) is essential for working with databases. SQL allows you to extract, manipulate, and analyze data from relational databases using queries. • Python: Python is a versatile programming language commonly used in data analytics. It offers numerous libraries and frameworks for data manipulation (e.g., Pandas), numerical computation (e.g., NumPy), and data visualization (e.g., Matplotlib and Seaborn). Python also has powerful Machine Learning libraries such as Scikit-​learn and TensorFlow.

With hundreds of tools preinstalled, the Kali Linux distribution makes it easier for penetration testers and other professionals to get started with security testing quickly. But with more than 600 tools in its arsenal, the Kali Linux can also be overwhelming. The new edition of this practical book covers updates to the tools, including deeper coverage of reverse engineering. Kali Linux is a distribution that is specifically tailored to a particular type of user— those who are interested in information security and the range of capabilities that fall under that incredibly broad umbrella. Kali Linux, as a distribution focused on security functions, falls into the desktop category, and there is no intention to limit the number of packages that are installed to make Kali harder to attack. Someone focused on security testing will probably need a wide variety of software packages, and Kali loads their distribution out of the gate. This may seem mildly ironic, considering distributions that focus on keeping their systems safe from attack (sometimes mistakenly called secure) tend to limit the packages through a process called hardening. Kali, though, is focused on testing, rather than keeping the distribution safe from attack.

Medical imaging is fundamental to modern healthcare, and its widespread use has resulted in creation of image databases. These repositories contain images from a diverse range of modalities, multidimensional as well as co-aligned multimodality images. These image collections offer opportunity for evidence-based diagnosis, teaching, and research. Advances in medical image analysis over last two decades shows there are now many algorithms and ideas available that allow to address medical image analysis tasks in commercial solutions with sufficient performance in terms of accuracy, reliability and speed. Content-based image retrieval (CBIR) is an image search technique that complements the conventional text-based retrieval of images by using visual features, such as color, texture, and shape, as search criteria. This book emphasizes the design of wavelet filter-banks as efficient and effective feature descriptors for medical image retrieval. Firstly, a generalized novel design of a family of multiplier-free orthogonal wavelet filter-banks is presented. In this, the dyadic filter coefficients are obtained based on double-shifting orthogonality property with allowable deviation from original filter coefficients. Next, a low complex symmetric Daub-4 orthogonal wavelet filter-bank is presented. A computer based system used for browsing, searching, and retrieving images from a sizable collection of digital images is called a content-based image retrieval (CBIR) system. Large archives of images and multimedia content have been created in recent years due to the rapid rise of digital computers, multimedia, and storage technologies.

Tableau, one of the most widely used visualization tools, helps in illustrating the ideas of data visualization and storytelling. Through Tableau’s Data Visualization and Storytelling feature, aspiring data scientists and analysts can develop their visual analytics skills and use them in both academic and business contexts. Data Visualization and Storytelling with Tableau enables budding data analysts and data scientists to develop and sharpen their skills in the field of visual analytics and apply them in business scenarios as well as in academic context. This book approaches the Data Visualization workflow from a practical point of view, emphasizing the steps involved and the outcomes attained. A major focus of this book is the application and deployment of real-time case studies. Later chapters in this book provide comprehensive coverage for advanced topics such as data storytelling, data insights, color selection in graphs, publishing in tableau public, and misleading visualizations. Thus, this book emphasizes the need to visually examine and evaluate data through stories and interactive dashboards that are made up of appropriate graphs and charts. The case studies covered in this book are a natural extension of the visualization topics that are covered in each chapter. This book is meant for data analysts, computer scientists/engineers, and industry professionals who are interested in creating different types of visualization graphs for a given data problem and drawing interesting insights from the plotted trends in order to make better business decisions in the future.

Radically improve the quality of your data visualizations by employing core principles of color, typography, chart types, data storytelling, and more. Everyday Data Visualization is a field guide for design techniques that will improve the charts, reports, and data dashboards you build every day. Everything you learn is tool-agnostic, with universal principles you can apply to any data stack. This book gives you the tools you need to bring your data to life with clarity, precision, and flair. You’ll learn how human brains perceive and process information, wield modern accessibility standards, get the basics of color theory and typography, and more. One of the most popular and powerful data visualization libraries for jаvascript is the free and open-source d3.js, also known as D3 or d3, which stands for “Data-Driven Documents.” If jаvascript and its asynchrony aren’t your jam, perhaps you’d prefer Python or R. While Python is an entire programming language, and R is a software environment specifically made for statistical analysis, both are free and open source, have a cult-like following among coders, and are great for data viz practitioners. Both R and Python have very friendly and approachable syntax, hence their considerable popularity. If you’re a statistician or data scientist, you probably already know R, and if you’re not, I’d wager you’d prefer Python. As for libraries to use in each, R users adore their ggplot/ggplot2 and Shiny, while Python users have many other options, including Seaborn, Plotly, and Matplotlib.
