  1. Artificial Intelligence Prabhas Chongstitvatana Chulalongkorn University prabhas.c@chula.ac.th

  2. AI : Past, Present, Future

  3. Why AI is popular today?

  4. Performance in "human task" • Tagging Faces • Search Music • Personal assistance • Play Go

  5. Tiny computer for 5 dollars

  6. Past Symbolic AI • based on Predicate logic • Physical Symbol Hypothesis Connectionist

  7. Physical Symbol Hypothesis "A physical symbol system has the necessary and sufficient means for general intelligent action." — Allen Newell and Herbert A. Simon • General Problem Solver

  8. General Problem Solver

  9. Means – Ends Analysis

  10. SHDRLU

  11. SHDRLU • Here is a famous demonstration of SHRDLU: • Person: Pick up a big red block. • Computer: OK. • Person: Grasp the pyramid. • Computer: I DON'T UNDERSTAND WHICH PYRAMID YOU MEAN. • Person (changing their mind): Find a block which is taller than the one you are holding and put it into the box. • Computer: BY "IT", I ASSUME YOU MEAN THE BLOCK WHICH IS TALLER THAN THE ONE I AM HOLDING. • Computer: OK. • Person: What does the box contain? • Computer: THE BLUE PYRAMID AND THE BLUE BLOCK. • Person: What is the pyramid supported by? • Computer: THE BOX. • Person: How many blocks are not in the box? • Computer: FOUR OF THEM.

  12. Example of logic system • Cyc • started in 1984 by Dough Lenat (ID3) • encyclopedia + everyday knowledge • (such as people will die) • in June 2012 the knowledge base contains 239,000 concepts and 2,039,000 facts • can be browsed on OpenCyc website

  13. OpenCyc

  14. Special Machines for Logic Systems • Japan Fifth Generation Computer System • Knowledge Information Processing systems" (appliedArtificial Intelligence) • 10 years project, start 1982, $400 millions • Logic system

  15. Connectionist • Artificial Neural Networks • Deep learning

  16. Artificial Neural Networks

  17. Machine learning • Machines with common sense

  18. Generate Music with GA GenJam

  19. Present • machine learning in computer vision • Alpha Go

  20. Object Recognition

  21. Deep Learning

  22. AlphaGo vs Lee Seidol, March 2016

  23. Alpha Go • "Mastering the game of Go with deep neural networks and tree search". Nature. 529 (7587): 484–489. • Deep learning • Monte Carlo Tree search

  24. Team work
