Making AI Great Again: Keeping the AI Spring Making AI Great Again: Keeping the AI Spring Lito Perez Cruz1 and David Treisman2 1Sleekersoft, 2 Warburton Crt., Mill Park, VIC 3082, Australia 2C F Gauss & Associates, PO Box 652, Templestowe, VIC 3106, Australia Keywords: Artificial Intelligence, Deep Learning, Agents. Abstract: There are philosophical implications to how we define Artificial Intelligence (AI). To talk about AI is to deal with philosophy. Working on the intersections between these subjects, this paper takes a multi-lens approach in examining the reasons for the present resurgence of interest in things AI through a range of historical, linguistic, mathematical and economic perspectives. It identifies AI’s past decline and offers suggestions on how to sustain and give substance to the current global hype and frenzy surrounding AI. 1 INTRODUCTION larly, the call AI’s rise which is what we have today as ”AI Spring”.

You are welcome to bring notes to the exam, so you could start by filling out this sheet with notes from lectures and the readings! Like the mid-term, the final exam will have two kinds of questions. 1) Multiple choice questions examining your knowledge of key concepts, terms, historical developments, and contexts 2) Short answer questions in which ask you to draw on things you’ve learned in the course (from lecture, readings, videos) to craft a short argument in a brief essay expressing your informed issue on a historical question 2. Sample Questions Multiple Choice: Mina Rees was involved in (and wrote about) which of the following computing projects? A) Silicon Valley start-ups in the dot-com period B) Charles Babbage’s Difference Engine C) Works Projects Administration Tables Project D) Federal funding for computing research after WWII Short Answer: (Your answers should be between 100-200 words, and keep to specifics (events, machines, developments, people) that demonstrate your knowledge of materials covered from the course) A) What are two historical factors important to the development of Silicon Valley’s technology industry after World War II? B) In what ways did the field of programming change (in terms of its status and workers) between World War II and the late 1960s? 3. Topics to Review: Below, is a list of ideas to review for the final exam, which covers material through the entire course.

To understand the impact AI will have on our lives, it is vital to appreciate the context in which the !eld was established. After all, statistics and state control have evolved hand in hand for hundreds of years. Consider computing. Its origins have been traced not only to analytic philosophy, pure mathematics and Alan Turing, but perhaps surprisingly, to the history of public administration. In “The Government Machine: A Revolutionary History of the Computer” from 2003, Jon Agar of University College London charts the development of the British civil service as it ballooned from 16,000 employees in 1797 to 460,000 by 1999. He noticed an uncanny similarity between the functionality of a human bureaucracy and that of the digital electronic computer.

Office hours will be over Zoom. Motivating artificial intelligence It is generally not hard to motivate AI these days. There have been some substantial success stories. A lot of the triumphs have been in games, such as Jeopardy! (IBM Watson, 2011), Go (DeepMind’s AlphaGo, 2016), Dota 2 (OpenAI, 2019), Poker (CMU and Facebook, 2019). On non-game tasks, we also have systems that achieve strong performance on reading comprehension, speech recognition, face recognition, and medical imaging benchmarks. Unlike games, however, where the game is the full problem, good performance on a benchmark does not necessarily translate to good performance on the actual task in the wild. Just because you ace an exam doesn’t necessarily mean you have perfect understanding or know how to apply that knowledge to real problems. So, while promising, not all of these results translate to real-world applications Dangers of AI From the non-scientific community, we also see speculation about the future: that it will bring about sweeping societal change due to automation, resulting in massive job loss, not unlike the industrial revolution, or that AI could even surpass human-level intelligence and seek to take control.

  • Artificial Intelligence the Next Digital Frontier?
    ARTIFICIAL INTELLIGENCE THE NEXT DIGITAL FRONTIER? DISCUSSION PAPER JUNE 2017 Jacques Bughin | Brussels Eric Hazan | Paris Sree Ramaswamy | Washington, DC Michael Chui | San Francisco Tera Allas | London Peter Dahlström | London Nicolaus Henke | London Monica Trench | London Since its founding in 1990, the McKinsey Global Institute (MGI) has sought to develop a deeper understanding of the evolving global economy. As the business and economics research arm of McKinsey & Company, MGI aims to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. The Lauder Institute at the University of Pennsylvania ranked MGI the world’s number-one private-sector think tank in its 2016 Global Think Tank Index for the second consecutive year. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on six themes: productivity and growth, natural resources, labor markets, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed the economic benefits of tackling gender inequality, a new era of global competition, Chinese innovation, and digital globalization. MGI is led by four McKinsey and Company senior partners: Jacques Bughin, James Manyika, Jonathan Woetzel, and Frank Mattern, MGI’s chairman. Michael Chui, Susan Lund, Anu Madgavkar, Sree Ramaswamy, and Jaana Remes serve as MGI partners.

  • Frameworks for Intelligent Systems
    Frameworks for Intelligent Systems CompSci 765 Meeting 3 Pat Langley Department of Computer Science University of Auckland Outline of the Lecture • Computer science as an empirical discipline • Physical symbol systems • List structures and list processing • Reasoning and intelligence • Intelligence and search • Knowledge and intelligence • Implications for social cognition 2 Computer Science as an Empirical Discipline! In their Turing Award article, Newell and Simon (1976) make some important claims: • Computer science is an empirical discipline, rather than a branch of mathematics. • It is a science of the artificial, in that it constructs artifacts of sufficient complexity that formal analysis is not tractable. • We must study these computational artifacts as if they were natural systems, forming hypotheses and collecting evidence. They propose two hypotheses based on their founding work in list processing and artificial intelligence.! 3 Laws of Qualitative Structure! The authors introduce the idea of laws of qualitative structure, which are crucial for any scientific field’s development: • The cell doctrine in biology • Plate tectonics in geology • The germ theory of disease • The atomic theory of matter They propose two such laws, one related to mental structures and another and the other to mental processes. 4 Physical Symbol Systems! Newell and Simon’s first claim, the physical symbol system hypothesis, states that: • A physical symbol system has the necessary and sufficient means for general intelligent action. They emphasize general cognitive abilities, such as humans exhibit, rather than specialized ones. This is a theoretical claim that is subject to empirical tests, but the evidence to date generally supports it.! 5 More on Physical Symbol Systems! What do Newell and Simon mean by a physical symbol system? • Symbols are physical patterns that are stable unless modified.
