[Takagi Laboratory] [Research Activity] [Educational Activity] [Academic Service] [Private] [ver.2004]

Dear my friends in the world,

I made this 2005 annual report as my seasonal greeting to my friends. Please enjoy it.
I hope that we keep in touch

Thinking of you from Japan on New Year Day, 2005

Takagi Laboratory

During the 2004 fiscal year (April, 2004 - March, 2005), Takagi Laboratory consists of two Bachelors, three Master students, and one doctoral student. But, a part-time Master student and a doctoral student are taking off university, so that only three students work for our lab actually.

In the 2005 fiscal year, four Master students and a Governmental scholarship student who will challenge the enrollment to doctoral course from Slovakia will enroll to our lab in April. The number of Bachelors to our lab from April is unknown so far, and how students taking off university will do from the 2005 fiscal year, too, but Takagi Lab will consists of seven students at least.

The biggest difference of Takagi Lab this year from past years is the number of postdoctoral researchers. Three postdoctoral researchers will support our research activity strongly: Dr. Shangfei Wang, COE postdoctoral researcher in July, 2004 - December, 2005, Dr. Raffi R. Kamalian, JSPS Postdoctoral Fellow in November, 2004 - November, 2006, and Dr. Shino Iwashita, March, 2005 - March, 2006. Postdoctoral researchers hired by Kyushu University have one-year contract, but we can expect their strong support in the 2006 fiscal year if they renew the contracts of employment.

I hosted Lecture Huidao Tang from China and Prof. Oswaldo Velez-Langs from Spain as Visiting Researchers in 2004.

Research Activity

I have been working on the combination of human factor and computational intelligence that I call as Humanized Computational Intelligence. Interactive evolutionary computation (IEC) is still a main keyword of my research for this direction. See a survey and tutorial paper of IEC research.

We, team members who are applying to governmental Grants-in-Aid for Scientific Research (not accepted yet, though), had symposiums on Humanized Computational Intelligence at Spa in January and August, 2004, and will have the third symposium in January, 2005. We had and will have longer discussion time more than presentation time in relax emotion in these symposiums and stayed/will stay a night together at a Spa hotel in Japanese style. We hope that our grant application will be accepted in 2005. I also hope that I can find research direction on Humanized Computational Intelligence that exceeds IEC on which I have researched.

Our IEC research in 2004 includes the following.

Our research publication in 2004 includes one book chapter, three journal papers, five international conference papers, one tutorial paper for a journal, and three domestic conference papers.

My targets in 2005 are:

  1. to experimentally show that extended IEC can optimize a target system with physiological feedback,

  2. to start new research on designing a deep-emotion enhancement filter based on measured physiological data of a human who is impressed by movies or music as an application of the above 1.,

  3. to spread the IEC technique for designing circuit, MEMS, or device including filing patents with UC Berkeley,

  4. to summarize the experimental data of mental health measurement and submit a journal paper, and extend our experimental subjects to persons of senile dementia,

  5. to evaluate the effectiveness of IEC-based medical image enhancement filter design with the help of medical doctors and students, quantitatively,

  6. to design policy and manual for IEEE SMC technical activity and let SMC continue their stable activity in technical aspects, and

  7. to make my own vision and mission for Humanized Computational Intelligence.

Educational Activity


I taught courses on computational intelligence, software engineering, data and signal compression, and other lab works in 2004.

I had a chance to give a lecture to undergraduate students who taking a course of System Optimization at BogaziciUniversity in Istanbul on December 16, 2004.

Academic Service

Prof. Iba and I were guest editors for the Special Issues on Interactive Evolutionary Computation at an international journal, New Generation Computing in 2003 and 2004. The issues will be published in Vol.23, No.2, February, 2005.

I was elected as a Board of Governors member of IEEE SMC Society for 2004-2006. I also start to serve for whole SMC Technical Committee as the Technical Committee Coordinator since the end of last year. I resigned the Soft Computing Chair under the SMC Technical Committee at the end of 2004 after six-year serve and passed its baton to Prof. Murata of Kansai University who significantly contributed for organizing Soft Computing Tracks at SMC2002, SMC2003, and SMC2004. I keep serving as an Associate Editor of IEEE Transactions on SMC, Part B.

This year is the final year for serving as a SOFT (Japan Society for Fuzzy Theory and Intelligent Informatics) Councilor.

We received a Paper Award from SOFT for the below paper and received it at SOFT General Meeting at FSS2004 in June, 2004:

Hideyuki Takagi, Takeo Ingu, and Kei Ohnishi,
"Accelerating a GA Convergence by Fitting a Single-Peak Function,"
J. of Japan Society for Fuzzy Theory and Intelligent Informatics, vol.15, no.2, pp.219-229 (2003)(in Japanese).

[ABSTRACT] The simplest approximation of GA landscape is a single-peak function such as a quadratic function or Gaussian function. As the peak position is expected to locate near the global optimum, this method approximates the GA landscape and adds the position of the peak as an elite individual into individuals in the next generation by replacing the poorest individual. If the elite is a better individual as expected, it contributes to accelerate GA convergence; if not, it is just one of many individuals and it may not make the GA convergence worse. We can say that this is a method of "low risk, high return".

Other academic activity in 2004 was giving a tutorial talk at GECCO2004. In 2005, it is scheduled to give plenary talks at WSTST2005 (Muroran, Japan in May), SMCia2005 (Helsinki in June), and KES2005 (Melbourne in September) and a tutorial talk at GECCO2005 (Washington DC in June).

My elder daughter enrolled Kobe Women's College in April, 2004, and younger daughter will take the enrollment examination to High School next month. The younger one will be an exchanging high school student in US for 10 months from this summer. My wife and I will back to the honeymoon days for 10 months.
