Book SynopsisAI and Writing is an introduction to Generative Artificial Intelligence (GenAI) and its emergent role as a tool for academic, professional, civic, and personal writing. Sid Dobrin examines GenAI from two perspectives: the conceptual and the applied. The conceptual approach asks readers to consider the function of GenAI in their writing and to consider the ramifications of its use as a writing tool especially the ethical, social, and material issues it raises. The applied approach offers guidance to assist readers in using GenAI responsibly and authentically. In consideration of the rapid evolution of GenAI and the many unsettled questions about its utility, this book leaves room for readers to adapt to shifting technological and institutional contexts.This book is intended for composition and writing-intensive courses, and for any readers with a general or professional interest in the role of GenAI in writing. While it's primarily designed for first-year writing courses, it's also applicable to courses in advanced writing, professional writing, technical writing, business writing, and writing across the curriculum, as well as writing-intensive courses in other disciplines. In other words, it can be used in any course in which students are required to produce texts.Trade Review“AI and Writing is a practical, just-in-time guide for students—and teachers—on the uses and limitations of Generative AI in writing. Just as importantly, it will prompt critical reflection about AI's role in the future of writing and writing education. An invaluable read for anyone who wants to better understand GenAI and its impact on education.” — Naomi Mardock Uman, Metropolitan Community College“Sid Dobrin’s AI and Writing offers engaging insights that cut through contemporary anxiety surrounding generative AI in education. This book adeptly navigates both the speculative and the practical landscape of digital technologies, demystifying the complexities of generative AI and presenting actionable insights. Dobrin’s writing is framed by a philosophical and ethical lens that makes this book relevant, accessible, and essential reading for educators and learners alike.” — Clare Dyson, RMIT University Adobe Creative Campus“Sid Dobrin has spent his career pushing us to see what comes next for writing, and AI and Writing offers yet another exciting glimpse around the corner.… Dobrin’s book offers educators and students alike a vantage point from which to engage writing’s future.” — Jason Crider, Texas A&M University“Whether you are preparing students and colleagues for the new world of writing with AI or just trying to help them catch up to what has happened since the release of ChatGPT, Sid Dobrin offers an essential resource. The speed of change in AI and writing can be intimidating, but Dobrin deftly captures the enduring questions, illuminates a longer history than some might realize for these technologies, and sets an agenda for thoughtful engagement with AI rather than a reactionary response.” — William Hart-Davidson, Michigan State UniversityTable of ContentsI.

Book SynopsisAn authoritative, accessible, and up-to-date treatment of deep learning that strikes a pragmatic middle ground between theory and practice.Deep learning is a fast-moving field with sweeping relevance in today’s increasingly digital world. Understanding Deep Learning provides an authoritative, accessible, and up-to-date treatment of the subject, covering all the key topics along with recent advances and cutting-edge concepts. Many deep learning texts are crowded with technical details that obscure fundamentals, but Simon Prince ruthlessly curates only the most important ideas to provide a high density of critical information in an intuitive and digestible form. From machine learning basics to advanced models, each concept is presented in lay terms and then detailed precisely in mathematical form and illustrated visually. The result is a lucid, self-contained textbook suitable for anyone with a basic background in applied mathematics. Up-to-date treatment of deep learning covers cutting-edge topics not found in existing texts, such as transformers and diffusion models Short, focused chapters progress in complexity, easing students into difficult concepts  Pragmatic approach straddling theory and practice gives readers the level of detail required to implement naive versions of models Streamlined presentation separates critical ideas from background context and extraneous detail Minimal mathematical prerequisites, extensive illustrations, and practice problems make challenging material widely accessible  Programming exercises offered in accompanying Python Notebooks

Book Synopsis'An invaluable companion for anyone who wants a deep understanding of what's under the hood of often inscrutable machines' Melanie Mitchell A rich, narrative explanation of the mathematics that has brought us machine learning and the ongoing explosion of artificial intelligenceMachine-learning systems are making life-altering decisions for us: approving mortgage loans, determining whether a tumour is cancerous, or deciding whether someone gets bail. They now influence discoveries in chemistry, biology and physics - the study of genomes, extra-solar planets, even the intricacies of quantum systems. We are living through a revolution in artificial intelligence that is not slowing down. This major shift is based on simple mathematics, some of which goes back centuries: linear algebra and calculus, the stuff of eighteenth-century mathematics. Indeed by the mid-1850s, a lot of the groundwork was all done. It took the development of computer science and the kindling of 1990s computer chips designed for video games to ignite the explosion of AI that we see all around us today. In this enlightening book, Anil Ananthaswamy explains the fundamental maths behind AI, which suggests that the basics of natural and artificial intelligence might follow the same mathematical rules. As Ananthaswamy resonantly concludes, to make the most of our most wondrous technologies we need to understand their profound limitations - the clues lie in the maths that makes AI possible.
