Ockham S Razors

This book uses philosophy, science and probability to analyse why simpler theories are better than theories that are more complex.

This book explores inductive inference using the minimum message length (MML) principle, a Bayesian method which is a realisation of Ockham's Razor based on information theory. Accompanied by a library of software, the book can assist an applications programmer, student or researcher in the fields of data analysis and machine learning to write computer programs based upon this principle. MML inference has been around for 50 years and yet only one highly technical book has been written about the subject. The majority of research in the field has been backed by specialised one-off programs but this book includes a library of general MML–based software, in Java. The Java source code is available under the GNU GPL open-source license. The software library is documented using Javadoc which produces extensive cross referenced HTML manual pages. Every probability distribution and statistical model that is described in the book is implemented and documented in the software library. The library may contain a component that directly solves a reader's inference problem, or contain components that can be put together to solve the problem, or provide a standard interface under which a new component can be written to solve the problem. This book will be of interest to application developers in the fields of machine learning and statistics as well as academics, postdocs, programmers and data scientists. It could also be used by third year or fourth year undergraduate or postgraduate students.

"In short, Life Is Simple is enthralling."--Michael Blastland, Prospect A biologist argues that simplicity is the guiding principle of the universe Centuries ago, the principle of Ockham’s razor changed our world by showing simpler answers to be preferable and more often true. In Life Is Simple, scientist Johnjoe McFadden traces centuries of discoveries, taking us from a geocentric cosmos to quantum mechanics and DNA, arguing that simplicity has revealed profound answers to the greatest mysteries. This is no coincidence. From the laws that keep a ball in motion to those that govern evolution, simplicity, he claims, has shaped the universe itself. And in McFadden’s view, life could only have emerged by embracing maximal simplicity, making the fundamental law of the universe a cosmic form of natural selection that favors survival of the simplest. Recasting both the history of science and our universe’s origins, McFadden transforms our understanding of ourselves and our world.

Discover the essential thinking tools you’ve been missing with The Great Mental Models series by Shane Parrish, New York Times bestselling author and the mind behind the acclaimed Farnam Street blog and “The Knowledge Project” podcast. This first book in the series is your guide to learning the crucial thinking tools nobody ever taught you. Time and time again, great thinkers such as Charlie Munger and Warren Buffett have credited their success to mental models–representations of how something works that can scale onto other fields. Mastering a small number of mental models enables you to rapidly grasp new information, identify patterns others miss, and avoid the common mistakes that hold people back. The Great Mental Models: Volume 1, General Thinking Concepts shows you how making a few tiny changes in the way you think can deliver big results. Drawing on examples from history, business, art, and science, this book details nine of the most versatile, all-purpose mental models you can use right away to improve your decision making and productivity. This book will teach you how to: Avoid blind spots when looking at problems. Find non-obvious solutions. Anticipate and achieve desired outcomes. Play to your strengths, avoid your weaknesses, … and more. The Great Mental Models series demystifies once elusive concepts and illuminates rich knowledge that traditional education overlooks. This series is the most comprehensive and accessible guide on using mental models to better understand our world, solve problems, and gain an advantage.

This collection of new essays explores the nature of explanation and causality. It provides a stimulating and wide ranging debate on one of the central issues that has concerned philosophers and scientists alike--the epistemological nature of their enquiries. The volume not only sheds light on some of the general questions involved, but also addresses specific problems involved in explanation in different fields--physics, biology, psychology and the social sciences. Explanation and its Limits is an up-to-date, sharply focused and comprehensive review for all philosophers, scientists and social scientists interested in methodology.

Ockham Explained is an important and much-needed resource on William of Ockham, one of the most important philosophers of the Middle Ages. His eventful and controversial life was marked by sharp career moves and academic and ecclesiastical battles. At 28, Ockham was a conservative English theologian focused obsessively on the nature of language, but by 40, he had transformed into a fugitive friar, accused of heresy, and finally protected by the German emperor as he composed incendiary treatises calling for strong limits on papal authority. This book provides a thorough grounding in Ockham's life and his many contributions to philosophy. It begins with an overview of the philosopher's youth and the Aristotelian philosophy he studied as a boy. Subsequent chapters cover his ideas on language and logic; his metaphysics and vaunted "razor," as well as his opponents' "anti-razor" theories; his invention of the church-state separation; and much more. The concluding chapter sums up Ockham's compelling philosophical personality and explains his modern appeal.

An understanding of psychology—specifically the psychology behind how users behave and interact with digital interfaces—is perhaps the single most valuable nondesign skill a designer can have. The most elegant design can fail if it forces users to conform to the design rather than working within the "blueprint" of how humans perceive and process the world around them. This practical guide explains how you can apply key principles in psychology to build products and experiences that are more intuitive and human-centered. Author Jon Yablonski deconstructs familiar apps and experiences to provide clear examples of how UX designers can build experiences that adapt to how users perceive and process digital interfaces. You’ll learn: How aesthetically pleasing design creates positive responses The principles from psychology most useful for designers How these psychology principles relate to UX heuristics Predictive models including Fitts’s law, Jakob’s law, and Hick’s law Ethical implications of using psychology in design A framework for applying these principles
