1. Deep Learning Recent breakthroughs offering machine learning with enhanced autonomous, adaptive and self-improving properties We developed several deep-learning technologies and applied them to handwriting recognition. Input Simple features Complex features Output Input Simple features Complex features Output Characteristic extraction Recognition Characteristic extraction Recognition Won Mandarin Handwriting Recognition Competition at ICDAR2013 3
2. Todai Robot Project National Institute of Informatics Grand Challenge (2011-2021) Goal: Provide young people with a dream, blaze new trail, and re-unify the artificial intelligence field subdivided in 1980 and afterwards through development of an AI system that can answer real questions of university entrance examination. We join Math Team. Subjects: Japanese, Foreign Language (English, ), Mathematics, Science (Physics, Chemistry, Biology, ), Social Study (History, Geography, Civics, ) 4 Source : http://21robot.org/
2. Todai Robot Project We developed computer algebra technologies and applied them to solving mathematical problems written in natural language. Find the radius of a circle with area 4π.?(r)[ C. circle(c) area(c) = 4π radius(c) = r ] Problem Language Understanding Logical Form Math Lexicon (dictionary) Deep Parsing Anaphora resolution Discourse analysis Math Knowledge Base Example of Entrance Exam: the University of Tokyo ( Todai ), 2009?(r)[ s. πs 2 = 4π s > 0 s = r ] r = 2 Formula Rewriting Solver Input Solver algorithms Answer circle(c) area(c) = πr 2 radius(c) = r Quantifier Elimination Groebner Basis Theorem Prover etc. Overview of Math Solver System Standard deviation: about 50-60 Apply the result to broaden the use of mathematical approach for solving problems in real world 5
3. Research on Human Brain Goal: Understand the mechanism of intuition Analysis of activation site in brain and its temporal pattern by observing blood flow Board-Pattern Perception Precuneus Decision of Next-Move Caudate Nucleus Neural Basis of Intuitive Best Next-Move Generation in Board Game Experts # Joint work with RIKEN Published in Science Apply the results to design Big Intelligence 6 (Comparison of professional, high-rank and low-rank amateur shogi players)
Conclusion Big Intelligence is an intelligent computing system which enriches personal life enhances corporate/community activities improves society through automating intelligent tasks Research Activities: Deep Learning Todai Robot Project Research on Human Brain To bring more changes to the world: Direct actuation to physical space can open up further possibilities. 7
