The Alignment Problem
''The Alignment Problem: Machine Learning and Human Values'' is a 2020 non-fiction book by the American writer Brian Christian. It is based on numerous interviews with experts trying to build artificial intelligence systems, particularly machine learning systems, that are aligned with human values. Summary The book is divided into three sections: Prophecy, Agency, and Normativity. Each section covers researchers and engineers working on different challenges in the alignment of artificial intelligence with human values. Prophecy In the first section, Christian interweaves discussions of the history of artificial intelligence research, particularly the machine learning approach of artificial neural networks such as the Perceptron and AlexNet, with examples of how AI systems can have unintended behavior. He tells the story of Julia Angwin, a journalist whose ProPublica investigation of the COMPAS algorithm, a tool for predicting recidivism among criminal defendants, led to wides ...

Brian Christian
Brian Christian (born 1984 in Wilmington, Delaware) is an American non-fiction author, poet, programmer and researcher, best known for a bestselling series of books about the human implications of computer science, including ''The Most Human Human'' (2011), ''Algorithms to Live By'' (2016), and '' The Alignment Problem'' (2020). Christian competed as a "confederate" in the 2009 Loebner Prize competition, attempting to seem "more human" than the humans taking the test, and succeeded. The book he wrote about the experience, ''The Most Human Human,'' became a ''Wall Street Journal'' best-seller, a ''New York Times'' editors' choice, and a ''New Yorker'' favorite book of the year. He was interviewed by Jon Stewart on ''The Daily Show'' on March 8, 2011.

In 2016, Christian collaborated with co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AlphaGo
AlphaGo is a computer program that plays the board game Go (game), Go. It was developed by DeepMind Technologies a subsidiary of Google (now Alphabet Inc.). Subsequent versions of AlphaGo became increasingly powerful, including a version that competed under the name AlphaGo Master, Master. After retiring from competitive play, AlphaGo Master was succeeded by an even more powerful version known as AlphaGo Zero, which was completely Self-play (reinforcement learning technique), self-taught without learning from human games. AlphaGo Zero was then generalized into a program known as AlphaZero, which played additional games, including chess and shogi. AlphaZero has in turn been succeeded by a program known as MuZero which learns without being taught the rules. AlphaGo and its successors use a Monte Carlo tree search algorithm to find its moves based on knowledge previously acquired by machine learning, specifically by an artificial neural network (a deep learning method) by extensi ...

Kirkus Reviews
''Kirkus Reviews'' (or ''Kirkus Media'') is an American book review magazine founded in 1933 by Virginia Kirkus (1893–1980). The magazine is headquartered in New York City. ''Kirkus Reviews'' confers the annual Kirkus Prize to authors of fiction, nonfiction, and young readers' literature. ''Kirkus Reviews'', published on the first and 15th of each month; previews books before their publication. ''Kirkus'' reviews over 10,000 titles per year. History Virginia Kirkus was hired by Harper & Brothers to establish a children's book department in 1926. The department was eliminated as an economic measure in 1932 (for about a year), so Kirkus left and soon established her own book review service. Initially, she arranged to get galley proofs of "20 or so" books in advance of their publication; almost 80 years later, the service was receiving hundreds of books weekly and reviewing about 100. Initially titled ''Bulletin'' by Kirkus' Bookshop Service from 1933 to 1954, the title was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Existential Risk
A global catastrophic risk or a doomsday scenario is a hypothetical future event that could damage human well-being on a global scale, even endangering or destroying modern civilization. An event that could cause human extinction or permanently and drastically curtail humanity's potential is known as an "existential risk." Over the last two decades, a number of academic and non-profit organizations have been established to research global catastrophic and existential risks, formulate potential mitigation measures and either advocate for or implement these measures. Definition and classification Defining global catastrophic risks The term global catastrophic risk "lacks a sharp definition", and generally refers (loosely) to a risk that could inflict "serious damage to human well-being on a global scale". Humanity has suffered large catastrophes before. Some of these have caused serious damage but were only local in scope—e.g. the Black Death may have resulted in the de ...

Effective Altruism
Effective altruism is a philosophical and social movement that advocates "using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis". People who pursue the goals of effective altruism, called , often choose careers based on the amount of good that the career achieves while donating to charities based on maximising impact. The movement developed during the 2000s, and the name was coined in 2011. Prominent philosophers influential to the movement include Peter Singer, Toby Ord, and William MacAskill. Several books and many articles about the movement have since been published, and the Effective Altruism Global conference has been held since 2013. As of 2022, several billion dollars have been committed to effective altruist causes. Popular cause priorities within effective altruism include global health and development, social inequality, animal welfare, and risks to the survival of humanity over the long-term future. Eff ...

Normative
Normative generally means relating to an evaluative standard. Normativity is the phenomenon in human societies of designating some actions or outcomes as good, desirable, or permissible, and others as bad, undesirable, or impermissible. A norm in this normative sense means a standard for evaluating or making judgments about behavior or outcomes. Normative is sometimes also used, somewhat confusingly, to mean relating to a descriptive standard: doing what is normally done or what most others are expected to do in practice. In this sense a norm is not evaluative, a basis for judging behavior or outcomes; it is simply a fact or observation about behavior or outcomes, without judgment. Many researchers in science, law, and philosophy try to restrict the use of the term normative to the evaluative sense and refer to the description of behavior and outcomes as positive, descriptive, predictive, or empirical. ''Normative'' has specialised meanings in different academic disciplines such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inverse Reinforcement Learning
Reinforcement learning (RL) is an area of machine learning concerned with how intelligent agents ought to take actions in an environment in order to maximize the notion of cumulative reward. Reinforcement learning is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning. Reinforcement learning differs from supervised learning in not needing labelled input/output pairs to be presented, and in not needing sub-optimal actions to be explicitly corrected. Instead the focus is on finding a balance between exploration (of uncharted territory) and exploitation (of current knowledge). The environment is typically stated in the form of a Markov decision process (MDP), because many reinforcement learning algorithms for this context use dynamic programming techniques. The main difference between the classical dynamic programming methods and reinforcement learning algorithms is that the latter do not assume knowledge of an exact mathematica ...
