" A jaw-dropping exploration of everything that goes wrong when we build AI systems and the movement to fix them.Today's machine-learning systems, trained by data, are so effective that we've invited them to see and hear for us8212 and to make decisions on our behalf. But alarm bells are ringing. Recent years have seen an eruption of concern as the field of machine learning advances. When the systems we attempt to teach will not, in the end, do what we want or what we expect, ethical and potentially existential risks emerge. Researchers call this the alignment problem. Systems cull r233 sum233 s until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole8212 and appear to assess Black and White defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And as autonomous vehicles share our streets, we are increasingly putting our lives in their hands. The mathematical and computational models driving these changes range in complexity from something that can fit on a spreadsheet to a complex system that might credibly be called artificial intelligence. They are steadily replacing both human judgment and explicitly programmed software. In best-selling author Brian Christian's riveting account, we meet the alignment problem's first-responders, and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they8212 and we8212 succeed or fail in solving the alignment problem will be a defining human story. The Alignment Problem offers an unflinching reckoning with humanity's biases and blind spots, our own unstated assumptions and often contradictory goals. A dazzlingly interdisciplinary work, it takes a hard look not only at our technology but at our culture8212 and finds a story by turns harrowing and hopeful. "

Biographisches: " Brian Christian is the author of the acclaimed bestsellers The Most Human Human and Algorithms to Live By , which have been translated into nineteen languages. A visiting scholar at the University of California, Berkeley, he lives in San Francisco." Rezension(2): "David A. Shaywitz,all Street Journal:The disconnect between intention and results8212" Rezension(3): "Stuart Russell, professor of computer science, University of California, Berkeley, and author of Human Compatible:A fascinating, provocative, and insightful tour of all the ways that AI goes wrong and all the ways people are trying to fix it. Essential reading if you want to understand where our world is heading." Rezension(4): "Cathy O'Neil, author of Weapons of Math Destruction:A new field has emerged that responds to and scrutinizes the vast technological shifts represented by our modern, virtual, algorithmically defined world. In The Alignment Problem, Brian Christian masterfully surveys the 'AI fairness' community, introducing us to some of its main characters,some of its historical roots in science, philosophy, and activism,and crucially, many of its philosophical quandaries and limitations." Rezension(5): "Mike Krieger, cofounder of Instagram:This is the book on artificial intelligence we need right now. Brian Christian takes us on a technically fluent (yet widely accessible) journey through the most important questions facing AI and humanity. It is thought-provoking and vital reading for anyone interested in our future." Rezension(6): "Jaan Tallinn, cofounder of Skype and the Future of Life Institute:An abundantly researched and captivating book that explores the road humanity has taken to create a successor for itself8212" Rezension(7): "Jennifer Pahlka, founder of Code for America and former deputy CTO of the United States:The Alignment Problem should be required reading for anyone influencing policy where algorithms are in play8212" Rezension(8): "James Barrat, best-selling author of Our Final Invention:A deeply enjoyable and meticulously researched account of how computer scientists and philosophers are defining the biggest question of our time: how will we create intelligent machines that will improve our lives rather than complicate or even destroy them? There's no better book than The Alignment Problem at spelling out the issues of governing AI safely." Rezension(9): "Martin Rees, emeritus professor of cosmology and astrophysics, University of Cambridge:Brian Christian is a fine writer and has produced a fascinating book. AI seems destined to become, for good or ill, increasingly prominent in our lives. We should be grateful for this balanced and hype-free perspective on its scope and limits." Rezension(10): "Kirkus Reviews:An intriguing exploration of AI, which is advancing faster than8212" Rezension(11): " Publisher's Weekly : July 27, 2020 Christian ( The Most Human Human ), a writer and lecturer on technology-related issues, delivers a riveting and deeply complex look at artificial intelligence and the significant challenge in creating computer models that “capture our norms and values.” Machines that use mathematical and computational systems to learn are everywhere in modern life, Christian writes, and are “steadily replacing both human judgment and explicitly programmed software” in decision-making. Some of those decisions, however, are unreliable, as Christian shows through scrupulous research. Facial recognition systems can be “wildly inaccurate for people of one race or gender but not another” and perform particularly poorly on identifying Black women correctly. Meanwhile, risk assessment software, which helps decide bail, parole, and even sentencing for criminal defendants, has been widely adopted nationwide without being extensively audited. Though it’s tempting to assume a doom-and-gloom outlook while reading of these problems, Christian refreshingly insists that “our ultimate conclusions need not be grim,” as a new subset of computer scientists “focused explicitly on the ethics and safety of machine-learning” is working to bridge the gap between human values and AI learning styles. Lay readers will find Christian’s revealing study to be a helpful guide to an urgent problem in tech." Rezension(12): "〈a href=http://www.kirkusreviews.com target=blank〉〈img src=https://images.contentreserve.com/kirkus_logo.png alt=Kirkus border=0 /〉〈/a〉: August 15, 2020 The latest examination of the problems and pitfalls of artificial intelligence. Computer scientist Christian begins this technically rich but accessible discussion of AI with a very real problem: When programming an algorithm to teach a machine analogies and substitutions, researchers discovered that the phrase man - doctor + woman came back with the answer nurse while shopkeeper - man + woman came back with housewife. An algorithm designed to examine and label photographs returned the caption gorillas when it depicted two African Americans. It happened that one of those men was a programmer himself, and he said, It's not even the algorithm at fault. It did exactly what it was designed to do. In other words, the algorithm is returning human biases, just as algorithms do when examining criminal records that often lead to machine-assisted recommendations for sentencing that overwhelmingly give Whites lighter punishments than Blacks and Latinos and color calibration programs for TVs and movie screens that are indexed to white skin. So how to teach machines to be reliable and bias-free? Christian considers models of human learning, such as those developed by Jean Piaget, whom Christian finds off on a couple of key assumptions but still a useful guide. He recalls that Alan Turing wondered why machine-learning programs were geared as if the machines were adults instead of children. Children, of course, learn by mistakes and accidents and by emulating adult doings that would lead to the interesting result, but can a machine? On that score, Christian ponders how self-driving vehicles are taught how to be autonomous, making decisions that are logical--but logical to a machine mind, not a human one. Perhaps, rather than painstakingly trying to hand-code the things we care about, writes the author, we should develop machines that simply observe human behavior and infer our values and desires from that--a task easier said than done. An intriguing exploration of AI, which is advancing faster than--well, than we are. COPYRIGHT(2020) Kirkus Reviews, ALL RIGHTS RESERVED. "
