Год: 2025
Страниц: 371
Язык: английский
Формат: pdf (true), epub
Размер: 10.1 MB
Power and Sample Size in R guides the reader through power and sample size calculations for a wide variety of study outcomes and designs and illustrates their implementation in R software. It is designed to be used as a learning tool for students as well as a resource for experienced statisticians and investigators. The book begins by explaining the process of power calculation step by step at an introductory level and then builds to increasingly complex and varied topics. For each type of study design, the information needed to perform a calculation and the factors that affect power are explained. Concepts are explained with statistical rigor but made accessible through intuition and examples. The book demonstrates calculations in R using examples. Only a basic proficiency in R is assumed. We use functions from the powertools package, which was developed as a companion R package to this book, as well as other packages. There are many packages for various types of power and sample size calculations available in R, and we try to summarize available resources in each chapter. The index includes not only concepts and topics but also the R functions and packages mentioned in the book. | |

This accessible and engaging textbook presents a concise introduction to the exciting field of Artificial Intelligence (AI). The broad-ranging discussion covers the key subdisciplines within the field, describing practical algorithms and concrete applications in the areas of agents, logic, search, reasoning under uncertainty, Machine Learning, neural networks, and reinforcement learning. Fully revised and updated, this much-anticipated third edition also includes new material on Deep Learning. Besides corrections of errors, this edition has new sections on data normalization, quality metrics for Machine Learning, data augmentation and a detailed introduction to convolutional networks, the now dominant technique of Deep Learning. Also new are an introduction to large language models such as ChatGPT and the GAN networks used for generative AI, followed by an assessment of how Deep Learning will change the world. Anyone who wants to put AI into practice should come equipped with firm knowledge of programming. Python is a useful language for this due to its relatively high level of abstraction and its many good libraries, particularly for Machine Learning. | |

 Название: The Cybersecurity Trinity: Artificial Intelligence, Automation, and Active Cyber Defense
Автор: Donnie W. Wendt
Издательство: Apress
Год: 2024
Страниц: 406
Язык: английский
Формат: pdf
Размер: 16.7 MB
This book explores three crucial topics for cybersecurity professionals: Artificial Intelligence (AI), automation, and active cyber defense (ACD). The Cybersecurity Trinity will provide cybersecurity professionals with the necessary background to improve their defenses by harnessing the combined power of these three concepts. The book is divided into four sections, one addressing each underlying concept and the final section discussing integrating them to harness their full potential. With the expected growth of AI and Machine Learning (ML), cybersecurity professionals must understand its core concepts to defend AI and ML-based systems. Also, most cybersecurity tools now incorporate AI and ML. However, many cybersecurity professionals lack a fundamental understanding of AI and ML. The book's first section aims to demystify AI and ML for cybersecurity practitioners by exploring how AI and ML systems work, where they are vulnerable, and how to defend them. | |

Страниц: 1056
Язык: английский
Формат: pdf (true)
Размер: 22.8 MB
This standard work on statistical methods in life sciences and medicine provides easily understandable, illustrative, and practical guidance to students, lecturers and practitioners alike, covering all necessary methods for targeted and careful data collection, analysis, and evaluation. In addition to offering advice and recommendations on study planning and analysis, numerous examples, cross-references, further references and a detailed index provide a comprehensive approach to statistics. The consistent use of the freely available programming language R further facilitates the entry for curious users and practitioners. R is primarily a programming language and programming environment for the statistical analysis of data. R can perform elementary mathematical operations on the one hand, but on the other hand, it also calculates sophisticated complex statistical functions. The use of R is simple and largely intuitive. R shows great flexibility in dealing with statistical functions and can also be extended for special methods. The R program offers versatile possibilities for the graphical preparation of data and results. | |

Almost everyone who comes into contact with ChatGPT is blown away by how smart it is. But having asked it to write a personalised birthday greeting in the style of Shakespeare, or got it to draw a picture of a badger playing snooker, most people want to know: how can ChatGPT make an actual difference to my life? That’s what this guide is here to answer. Over the following 130 pages, we will reveal dozens of ways in which you can put ChatGPT to practical use. Whether that’s through help with running your business, creating a fully automated smart home, or bringing your ideas for apps to life, we’ll show you how ChatGPT can make a difference. One of the great strengths of ChatGPT is that it’s both able to break down complex tasks into digestible Plain English, or even - in the case of writing computer code, for example - do the job for you. However, you still need to know how and where find to find the various ChatGPT tools that make these amazing features happen. You also need to be able to craft the prompts that give you the best possible chance of achieving the desired output. | |

Now in its second edition, R by Example is an example-based introduction to the statistical computing environment that does not assume any previous familiarity with R or other software packages. R functions are presented in the context of interesting applications with real data. The purpose of this book is to illustrate a range of statistical and probability computations using R for people who are learning, teaching, or using statistics. Specifically, it is written for users who have covered at least the equivalent of (or are currently studying) undergraduate level calculus-based courses in statistics. These users are learning or applying exploratory and inferential methods for analyzing data, and this book is intended to be a useful resource for learning how to implement these procedures in R. The new edition includes expanded coverage of ggplot2 graphics, as well as new chapters on importing data and multivariate data methods. | |
