Personal History:

  • Ryohei Nakano received his Bachelor of Engineering and Doctor of Engineering in Mathematical Engineering from the University of Tokyo.
  • After graduation he joined Nippon Telegraph and Telephone Corporation (NTT) and worked for its research laboratories for 28 years in the field of data processing, computer science, and artificial intelligence.
  • After that, he moved to Nagoya Institute of Technology as a full professor at the Department of Computer Science, and then moved to Chubu University as a full professor at the Department of Computer Science.
  • His research interests have been focusing on learning algorithms in the fields of machine learning and neural information processing, and he has invented with his colleagues more than 20 innovative learning algorithms. He published more than 50 journal papers, more than 100 conference papers, several book chapters, and got several academic paper awards. The number of citations for his papers amounts to more than 6,000 according to Google Scholar.
  • playing shogi (Japanese chess): Qualified as amateur third dan. Nowadays my favorite professional player is the young super-genius Sota Fujii. It's so thrilling and fascinating to watch his games on net TV with AI evaluation. I feel that professional shogi players and researchers are alike, struggling to find the best moves to get through the difficulties. My brain was greatly activated by playing with computer shogi programs.
  • listening to guitar music: The following are among my favorite plays on YouTube.
    supreme legend Narciso Yepes, whose guitar led me in my youth into the world full of enchantment and fantasy,
    true genius John Williams,
    noble maestro David Russell, and
    marvelous talent Celil Refik Kaya, Yamandu Costa.
  • having English tea: mainly darjeeling produced in the tea gardens such as Margaret's Hope, Rohini, and Castleton.
  • learning English: It's a fun to learn English, at the same time, we can learn the world history and investigate the world mysteries from ancient to modern. My tutors are English Journal, thought-provoking ambitious books, and Quora Digests. The more we learn, the more deeply we feel that we know nothing about them.
  • getting to know prehistoric civilizations: Who on earth built them? Our planet is full of mysteries. My favorite materials are
    exquisite books by Graham Hancock,
    ambitious TV series Ancient Aliens, and
    many relevant informative videos on YouTube.
