Alan Turing Einstein of computer science Matjaž Gams Institut “Jožef Stefan” JSI, AMT 11.10.2012 1 100-anniversary - - ACM Turing Centenary Celebration to Be Webcast Live! 29.5.2012 Alan Turing Centenary Conference, 22.-25.6.2012 Več 10 konferenc v večini držav sveta Več novih knjig - Specialna številka revije Informatica 100 YEARS OF ALAN TURING AND 20 YEARS OF SLAIS - Conference on 100 YEARS OF ALAN TURING AND 20 YEARS OF SLAIS, 11 October 2012, Ljubljana, Slovenia To be held at the 15th International Multiconference Information Society IS-2012 22.6.2012 2 Important years 1912 - birth 1936 – Turing machine 1932-42 - Enigma 1950 – birth of AI, Turing test 1954 - death 2007 - Donald Michie died 2009 – official rehabilitation 2012 - centenary JSI, AMT 11.10.2012 3 1936 – Turing machine, TM Abstract computing machine Can compute anything computable Formalizes the concept of algorithm Universal Turing machine can simulate all other TMs – universal TM, UTM Church-Turing thesis: “everything algorithmically computable is computable by a Turing machine." Gödel’s 1st theorem, decidability Independent of time, HW Universal concept, like Einstein’s relativity JSI, AMT 11.10.2012 4 „Stronger than“ Turing hypercomputer TM with oracle Quantum computer? Accelerating TS Multiple TM (worlds) 22.6.2012 5 Multiple worlds Schrëding equation, Heisenberg’s principle, collapse On the other hand, the collapse is considered as redundant in •the Bohm interpretation •the Many-Worlds Interpretation Multiverse Occam’s razor? 100x black matter needed String theory 22.6.2012 6 1932-42 - Enigma German coding machine Turing led the decoding of Enigma Designed „bombe“ Donald Michie in the team Web source: - One of the most important non-military discoveries in WW2 - Saved Nx1000 lives - Shortened WW2 by M months JSI, AMT 11.10.2012 7 1950 – birth of AI, Turing test Turing, Alan (October 1950), "Computing Machinery and Intelligence", Mind. What can computers do? Can they think, love …? „Strong AI“ (GOFAI) computer can do anything a human can Turing: Intelligent behaviour presumably consists in a departure from the completely disciplined behaviour involved in computation. Machine intelligence - 1956 McCarthy AI JSI, AMT 11.10.2012 8 1950 – birth of AI, Turing test Turing, Alan (October 1950), "Computing Machinery and Intelligence", Mind. Turing test – TT too hard or too simple? "Fair" Turing test Total TT – TTT, visual TT Total total TT – TTTT Loebner test 1991CAPTCHA, Jeopardy 2011 Searl’s Chinese room JSI, AMT 11.10.2012 9 Kurtzweil Kurtzweil Processing power People Computers Information society Flynn +30 + = Drake’s equation Computers Human Time HUMAN/COMPUTER INTELLIGENCE 10 1954 – death 2009 – official rehabilitation on behalf of the British government, and all those who live freely thanks to Alan's work I am very proud to say: we're sorry, you deserved so much better JSI, AMT 11.10.2012 11 2007 - Donald Michie With Turing on the Enigma project, first director of any AI department in the world in 1965, was director at the Turing institute where several Slovenian researchers studied for a while, honorary member of JSI, SAZU … Ivan Bratko, father of Slovenian AI, Donald was 1 month per year in Ivan’s room at JSI. Now at JSI Turing’s room, Donald Michie’s room Sobotna priloga Dela: Let this be in memory of Donald Michie as Turing’s contemporary and our dear colleague, and the extreme genius Alan Turing that marked the lives of every human in the world as hardly anybody. JSI, AMT 11.10.2012 12 Fame Lady Gaga Mozart, Einstein 400 millions 40 millions / 9920 Alan Turing 4 millions / 1677 Most people on streets not familiar (modest improvement since centenary events) Invented modern computing and artificial intelligence. „Einstein“ of computer science 1966- ACM Turing award Equivalent to Nobel prize Street in Manchester (City) JSI, AMT 11.10.2012 13 The meaning In most of the devices around you there are one to tens of TMs. One of the people that best influenced the progress of human civilization. Like Einstein. JSI, AMT 11.10.2012 14 Alan Mathison Turing Thank you JSI, AMT 11.10.2012 15
