![]() Fry builds upon the foundation of the early chapters and introduces additional concepts like decision trees, algorithmic errors, sensitivity and precision, neural networks, Bayes' theorem, and more. The remaining chapters-justice, medicine, cars, crime, art- look at specific applications for algorithms and data. Fry is careful to highlight many of the critical questions that need asking: What are the underlying assumptions of a particular algorithm? How is it biased? Why is personal data being collected about me? How is it being used? What are the incentives for the data collector? ![]() Data are the inputs that machine algorithms make use of the output predictions, decisions, classifications and more. Algorithms are the logical sets of instructions that computers use to perform a task. The first two chapters of the book cover two key concepts: algorithms and data. As a result, “Hello World” serves an an excellent primer for anyone seeking to better understand the implications of our highly algorithmic future. Fry takes a complicated and highly technical subject and deftly presents, in plain English, the key technical concepts and pressing ethical and moral considerations. Hello World: Being Human in the Age of Algorithms by Hannah Fry (2019) is a layperson’s guide to the important subject of Artificial Intelligence, machine learning, automation and algorithms. ![]()
