About my name

My family name is Ide, and my given name is Tsuyoshi (meaning a strong guy). Please call me Ide-san. I often spell my name as Ide, but both with and without the accent are okay. In kanji, it spells as Ide.

In Japan, it is common to call another person's name by attaching a suffix "-san" to his/her family name. In my case, it is "Ide-san", which I prefer. In the business situations and most of the daily situations, it is  rare (even impolite) in Japan to use given names to call other people.

Current research

Since 2003, I have been working on data mining and machine learning research at IBM Research - Tokyo. My recent research interests include:

For the details, see DBLP and the publication page.


My academic background is mechanical engineering and theoretical physics. I graduated from Tomakomai National College of technology and Tohoku University in mechanical engineering in 1990 and 1993, respectively.

After the first year of the graduate school, I decided to change my major to theoretical physics, and entered Department of Physics, Graduate School of Science, University of Tokyo in 1995. I received my M.Sc and Ph.D in theoretical solid state physics there in 1997 and 2000, respectively, working with Prof. Akio Kotani. My thesis was one of the earliest theoretical studies on "nonlocal screening effects" in resonant inelastic X-ray scattering phenomena in strongly correlated electronic systems.


I joined the display technology group, IBM Research - Tokyo, in 2000. For the first couple of years, I had been working on numerical study on liquid crystal displays (LCDs). The most successful work over this period was a dot pattern generation technique to optimize the configuration of micro light scatterers of LCDs (see the project page).

Since 2003, I have engaged in a number of data mining projects at IBM Research. For more information, see the project page and my publication list (see also DBLP).
